Summary: potential, the potential gradient along each of the branches ABC and ADC are equal initially and finally. This implies that the potential drop across each of the non-inductive resistances Ri and Re are equal. Therefore, the ratio of the potential differences across the two condensers Ci and Ce is equal to the ratio of their capacities. Sauty’s method provides a way to measure the capacity of a condenser by comparing it with another known capacity using a Wheatstone’s network. The charging and discharging process of a condenser in a circuit is governed by the time constant of the circuit, which determines how quickly or slowly the condenser reaches its maximum charge. Kirchoff’s laws play a crucial role in analyzing and solving complex circuits with multiple components.
