Question

Find the potential difference between points A and B of the system shown in Fig. 3.19 if the emf is equal to  = 110 V and the capacitance ratio C₂/C₁ = η = 2.0.

Answer 1

Let us distribute the charges, as shown in the figure. Now, we know that in a closed circuit, - Δφ = 0 

So, in the loop, DCFED,
