Question

If the plates of a parallel plate capacitor connected to a battery are moved closer to each other, then:

A. the charge stored in it increases.

B. the energy stored in it decreases.

C. its capacitance increases.

D. the ratio of charge to its potential remains the same.

E. the product of charge and voltage increases.

Choose the most appropriate answer from the options given below:

Vishal Gupta · Accepted Answer

A. At constant V (battery connected), C = \frac{\varepsilon0 A}{d} rises as d falls, so Q = CV rises and U = \frac12 CV^2 rises; Q/V = C increases; QV increases. A, C and E are correct; B and D are false.
