2 天之前· The flashbulbs used in photography work by charging a capacitor with a battery and then discharging that capacitor rapidly through the flashbulb. If a flashbulb capacitor discharges (10 text{ J}) of energy and a flashbulb battery provides a (15 text{ V}) potential, find the capacitance of the flashbulb capacitor.
Charging a capacitor isn''t much more difficult than discharging and the same principles still apply. The circuit consists of two batteries, a light bulb, and a capacitor. Essentially, the electron current from the batteries will

When connected to a battery, the capacitor stores electrostatic energy. This energy is in the form of charge on its plates which raises the potential difference between the plates. When required, this capacitor can release this stored energy and gets discharged. A capacitor is charged by connecting it to a voltage source and a resistor.
Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other. The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage.

All you need to charge a battery from a capacitor is to have more voltage charged on the capacitor than the voltage of the battery. The size will only affect how much time the capacitor will charge the battery. If you could charge the capacitor over and over and discharge it into the battery every time it was full it would eventually fully

No, a capacitor cannot charge a battery effectively. Capacitors store and release energy quickly, while batteries store energy for longer durations. When a capacitor is connected to a battery, it can transfer energy quickly, but

When you connect a battery to a capacitor, a "real" circuit has at least four components in series: Any wire has inductance, since current flowing through it will induce a magnetic field. It is possible to have wires without resistance - we call them superconductors. So let''s look at a circuit that has no resistance, and just the other three.
No headers. In Section 5.19 we connected a battery to a capacitance and a resistance in series to see how the current in the circuit and the charge in the capacitor varied with time; In this chapter, Section 10.12, we connected a battery to an inductance and a resistance in series to see how the current increased with time.We have not yet connected a battery to (R), (C), (L) in series.
When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other. The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage. Charging the capacitor stores energy in the electric field
Capacitor charging involves the process of storing electrical energy in a capacitor. When a capacitor is connected to a power source, such as a battery or a power supply, current flows into the capacitor, causing it to charge. The charging process is governed by the relationship between voltage, current, and capacitance.
All you need to charge a battery from a capacitor is to have more voltage charged on the capacitor than the voltage of the battery. The size will only affect how much time the capacitor will charge the battery.
Yes, capacitors can be charged using batteries or any other direct current (DC) power source. However, it’s essential to ensure that the voltage rating of the capacitor is not exceeded during charging. What happens if you overcharge a capacitor?
A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts.
DC charging is one of the most common methods of charging capacitors. In this method, a direct current (DC) power source is connected to the capacitor, allowing current to flow from the source into the capacitor. During DC charging, the voltage across the capacitor gradually increases as charge accumulates on its plates.
Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts. If a capacitor is connected to a DC power supply outputting 15 volts, it will charge up to 15 volts.
