Investigating charge and discharge of capacitors: An experiment can be carried out to investigate how the potential difference and current change as capacitors charge and discharge. The method is given below: A circuit is set up as shown below, using a capacitor with high capacitance and a resistor of high resistance slows down the changes (higher time constant) so it is easier to
By observing how long the red LED stays lit, you can get a hands-on understanding of how the current-limiting resistor R1 affects the charging and discharging of the capacitor. This can help deepen your understanding of the factors that determine the charging time of a capacitor.
In this experiment, instead of merely discharging an already charged capacitor, you will be using an Alternating Current (AC) "square wave" voltage supply to charge the capacitor through the resistor many times per second, first in a positivedirection and then in a negative direction.
As the capacitor discharges, the stored charge decreases, causing a gradual drop in voltage across the capacitor and an exponential decrease in the discharge current. As a result, the brightness of the green LED quickly dims and eventually goes out. The larger the capacitance and the resistance of the current-limiting resistor R2, the longer the discharge time of the capacitor
Objectives of this experiment 1. Estimate the time constant of a given RC circuit by studying Vc (voltage across the capacitor) vs t (time) graph while charging/discharging the capacitor.
