Q1:

Two capacitors of 2 μF and 4 μF capacitance are connected in series across a 30 V dc battery. After the capacitors have been charged, the voltage across them will be

A 15 V each

B 10 V and 20 V

C 20 V and 10 V

D 30 V each

ANS:C - 20 V and 10 V

Charge will be the same. Since Q = C V voltage will be inversely proportional to Q. Hence 20 V and 10 V.
