Three capacitors of value 6, 3 and 9 uF are joiaccording to the circuit and then the combination isconnected with a battery of 10 volt. The potentialdifference across the third capacitor plates will bened6uF(1) 4 v(3) 6 V(2) 5 V(4) 2 V

Answer»

Ceq of parallel capacitor is = 6+3 = 9μF so Ceq of circuit = 9*9/(9+9) = 9/2μF

now Q = CV = 45C

so, PD across 9μF = Q/C = 45/9 = 5V

option 2
