Question

3 capacitors of capacitance 2pf 3pf and 4pf are connected in parallel?
1.calculate the capacitance of combination?
2.calculate the charge on capacitor if the combination is connected to 100v supply?

Answer 1

Capacitance in parallel add up just like resistors in series. Also you can think of it like having thier total area increased.

1. Total/Equivalent Capacitance = (2+3+4) pF = 9 pF.

2. Charge Q = C x V = 9x100 pC = 900 pC
