I tested the positive and negative terminals of several battery connectors of typical household electronics such as remote controls and my digital scale. No continuity. Apparently I am rusty
So last night I decided to pull out the battery and give it a full charge. While it was out I took a multimeter (which thanks to the Navy I am very familiar with) and read resistance to ground on the positive battery cable. Read zero OHMS. Negative battery cable to ground is also zero ohms. Positve to negative battery cable is zero ohms.
I know I have a short, measure the resistance between the positive battery lead and the negative lead without the battery connected I have no resistance. Nor is it open, as the needle on the meter deflects all the way to
Why is there continuity between the negative and the positive terminals of both the RAMPS and the power supply? Furthermore, why is there continuity on RAMPS with only b/w one positive and the two negative terminals and not with the second positive? Just a side note my multimeter does not beep when I connect the negative and the positive
Here''s the other odd thing: If I set the multimeter to Ohms and put the black probe on the open ground wire and the red probe on the negative battery terminal, I get no resistance. If I move
1. Voltage b/w battery positive lead and frame--- No voltage (expected 12V) 2. Continuity/resistance b/w battery negative lead and frame-- Open circuit. Probably a contact issue at the frame 3. Voltage b/w battery negative terminal and engine block-- Expected close to 0V, but got a large voltage difference.
Connect the black lead of the multimeter to the negative battery terminal. The red lead should be connected to the positive battery terminal. Step 3: Check voltage readings. With the multimeter connected to the battery terminals, check the voltage readings on the multimeter display. The voltage reading should be between 12.4 to 12.6 volts.
Specifically, I would like to know if the Legnum electrical system is such that there is continuity between the negative battery terminal (which is connected to chassis
If the isolation leakage errors happen at both positive terminal and negative terminal of a high-voltage battery, the circuit diagram is as shown in Figure 2-1. Here, R. ISOP. represents the parasitic insulation resistance between high-voltage battery positive terminal and chassis ground, while R. ISON. represents the parasitic insulation
positive integer. The electron carries one unit of negative charge, qelectron =−e, and the proton carries one unit of positive charge, qproto n =+e . Voltage Sources Batteries, generators, power supplies are devices that convert some other form of energy into electrical energy. When the terminals of a battery are connected to a wire, forces
I measured resistance between disconnected battery cables after seeing a big drop in battery voltage. Shouldn''t the resistance be infinite or very large, in the many megohm
Q: When we connect the positive and negative terminals to a multimeter we have continuity should we have continuity when there is no battery hooked upAnd the alternator is not installed It is certainly possible that you have...

My batteries would die in like 4 min. so i checked and had continuity between both battery terminals. I isolated the problem by eliminating items from the loop one at a time and rechecking the continuity. How many ohms do you measure between the positive and negative cables? late 99'' F350, Crew cab, SRW, 4guage pillar pod, combo driving/fog
I know that if you have two batteries, battery A and battery B, and connect the negative terminal of battery A to the positive terminal of battery B, there is no potential difference. If you consider the negative and positive terminals of the same battery, the potential difference exists (say 1.5V).
To the point, my question: Using a multimeter in place of the battery, what should the resistance reading be between the negative and positive battery cables? (This is on a ''99.) Background: Like many of you, I''ve been
When corrosion occurs on a car battery terminal, its resistance to electrical power increases, and the battery can even leak battery acid. This makes your car battery work poorly. Differentiating between a positive and negative car

When I measured the resistance negative-negative and positive-positive on the battery, it was infinite. But when I measure it through opposites, there is no resistance. Why is

Negative resistance, like positive resistance, is measured in ohms. Conductance is the reciprocal of resistance. [33] [34] A battery has negative static resistance [20] [23] [32] (red) over its normal operating range, but positive differential
During those needle penetration tests, the following parameters were measured 1) cell voltage, 2) voltage between needle and positive terminal (V NP), 3) voltage between needle and negative terminal (V NN), 4) force applied on needle and 5) temperatures on the surface of cells (on vent, positive and negative terminal) using K-type thermocouple
V : is the voltage of the battery. I : is the current that flow in the wires, the resistor, and the led. R : is the total resistance of the circuit. Let''s calculate it first then understand why the resistor is at the positive terminal: You are using 2
Current as we draw it flows from positive battery terminal into negative battery terminal. Your model of resistors is not correct. Ohm''s law says U=R*I so if there is a current through resistance it will drop voltage. Voltage divider works because full battery voltage must be over the two resistors and equal current flows via both resistors.
You need to hook the negative back up and take a multimeter and put it on the amperage sitting and put the one cable on the positive side of the battery and the other cable
When this happens, voltage can drop, and if load characteristics are peculiar, it might appear as negative voltage. For example, a 12V battery may show a voltage drop in a high-drain scenario. Reversed Battery Connections: Reversed battery connections occur when the positive and negative terminals of a battery are connected incorrectly.
Set the voltmeter to read ohms (resistance) and probe the battery''s negative stud and ground connection on the accessory (the ground terminal on an amp, for example). If you have a reading less than five ohms, the ground is okay. If the resistance is okay but the accessory still isn''t working right, set the voltmeter to DC current (voltage).
Prior to installing the new cables, I took a resistance (ohm) reading from the house battery negative terminal to the chassis. The measurement fluctuated between 90 and 100 ohms. I installed the new ground cable and that brought it down to 15 to 20 ohms. I measured between the negative terminal and next to where I mounted the wire to the chassis.
If you''re asking something like does my negative wire from my battery pack to the busbar need to be the same length as the positive wire from the battery pack to the busbar, than the answer is no. Blue wires do not need to be the same length as red wires in your diagram. Now for a comment on the battery switch.
Zero resistance would be perfect continuity. Measuring resistance between the positive and negative cables with them off of the battery will show an extremely high resistance due to having the voltage from the meter being forced to travel through all different types of resistors before getting back to the meter.
In the context of telecom, the negative terminal of a battery is used to provide -48 volts, while the positive terminal is grounded. Batteries are arranged in series to achieve the desired voltage (48V), and then more batteries are connected in parallel to provide long-lasting current for the same output. Do not confuse this with the general usage of positive and negative terminals in other contexts.
For those interested, the answer to my original question is NO – there should not be any continuity between the positive and negative battery terminals when the battery is unplugged (as this would indicate a short circuit!).
Let's calculate it first then understand why the resistor is at the positive terminal: You are using 2 * AA battery. Each AA battery has 1.5 volts. It means the total voltage is 3 volts because you are using two batteries. V = 3 volts I assume that you use 100 ohm resistor. The current that should flow in the circuit = 3 / 100 = 0.03 ampere
The real electrons moves from the negative terminal to positive terminal. But that does not mean we should put the resistor at the negative terminal. Current pass or flow inside the wire and If you want to put something to interrupt it or make it slow down, you can put it in any place in series with the wire and it will interrupt the current.
The energy is flowing from the postive to negative: It limits it to the correct voltage to not damage the LED. Or The energy is flowing from the negative to postive and this example is showing the voltage pass through the LED then uses the resistor to eliminate the remaining voltage before it reaches the postive terminal.
