Question

The equivalent capacitance between points A &B–

• A. (a) C
• A. (b) 2 C
• A. (c) 3 C
• A. (d) 4 C

Answer 1

(b)

All the 3C capacitors are in series

+ $\frac { 1 } { 3 \mathrm { C } }$ + = $\frac { 1 } { \mathrm { C } _ { \mathrm { eq } } }$ \ C_eq = C

C and C are in parallel \ C_eq = 2C
