Question

A condenser of 2μF capacitance is charged steadily from 0 to 5 C.Which of the following graph represents correctly the variation of potential difference (V) across it’s plates with respect to the charge (Q) on the condenser?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

Q=CV
V=$\frac{1}{C}$×Q
A straight line with slope=$\frac{1}{C}$
Slope=$\frac{1}{C}$=$\frac{1}{C}$×10−6
=5×105
So, the correct graph will be A
