Question

The capacitance of the system of parallel plates shown in the figure is

• A. `
• B. $\frac { 2 \varepsilon _ { 0 } A _ { 1 } A _ { 2 } } { \left( A _ { 2 } - A _ { 1 } \right) d }$
• C.
• D. $\frac { \varepsilon _ { 0 } A _ { 2 } } { d }$

Answer 1

Answer: (C)

Answer 2

Since the electric field between the parallel charge plates is uniform and independent of the distance, neglecting the fringe effect, the effective area of the plate of area A₂ is A₁. Thus the capacitance between the plates is

C =
