Five conducting parallel plates of area A are separated by distance d as shown. Plates 2 and 4 are connected by a wire, and a cell of emf E is connected between A and B. Find the charge that flows through the cell.

Question

G1 Physics · Accepted Answer

Find the equivalent capacitance between A and B from the plate connections. The charge drawn from the cell is Q = [2ε₀A/(3d)]E = 2ε₀AE/(3d). Hence option B.
