Question

Voltage applied on a capacitor is increased v to 2V then (a)Q remains the same, C double (b) q is doubled c is doubled (c) C remains the same Q is doubled (d) both Q and C remains same

Answer 1

Hii Students,

◆ Answer -

(c) C remains the same Q is doubled

◆ Explaination -

Voltage across the capacitor is given by -

V = Q/C

Here, Voltage (V) is -

• directly proportional to charge (Q)
• inversely proportional to capacitance (C)

Therefore, voltage applied on capacitor is doubled -

1. when Q is doubled keeping C constant
2. when C is halved keeping Q constant

Thus, from the given options, (C) is most correct.

Best luck...

Answer 2

Answer:

C remains the same Q is doubled
