Question

Calculate the equivalent capacitance between a & b –

• A. (a) 3 $\frac{\in_{0}A}{d}$
• A. (b) 2 $\frac{\in_{0}A}{d}$
• A. (c) $\frac{\in_{0}A}{d}$
• A. (d) $\frac{\in_{0}A}{2d}$

Answer 1

(a)

C₁ = × K₁ = 2C₀

C₂ = × K₂ = 4C₀

C₃ = × K₃ = 6C₀

C₄ = × K₄ = 4C₀

C₁,C₂ & C₃ are in parallel and C₄ is in series with C₁,C₂ & C₃

\ C₁ || C₂ || C₃ ® 2C₀ + 4 C₀ + 6C₀ = 12C₀

C_eq = $\frac { 12 \mathrm { C } _ { 0 } \times 4 \mathrm { C } _ { 0 } } { 16 \mathrm { C } _ { 0 } }$ = 3C₀ =
