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.
tudy the adiabatic charging of a capacitorIs there no way of eliminating or reducing the dissipation of energy 1 2 2CV in charging of a ca acitor? The answer is yes, there is a way. Instead of charg-ing a capacitor to the maximum voltage V0 in a single step if you charge it to this voltage in small step
(Why?) You can check this experimentally. The trick is to first keep the charging voltage to V0/2, let the capacitor charge for a time much greater than RC of the circuit, disconnect the power supply, increase its voltage to V0, recon ect it and let the capacitor charge to V0. Plot I2, t curves for the two parts and find out

Charging of a Capacitor – Formula, Graph, and Example
When the switch S is closed, the capacitor starts charging, i.e. a charging current starts flowing through the circuit. This charging current is maximum at the instant of switching and decreases gradually with the increase in the voltage across the capacitor. Once the capacitor is charged to a voltage equal to the source voltage V, the charging ...
