A constant potential difference is applied across the, Ask an Expert

Academics

A constant potential difference is applied across the plates of a parallel-plate capacitor. Neglecting any edge effects, the electric field inside the capacitor is:

a) constant

b) Varying as one over r squared

c) Decreasing as one moves from the positive to the negative plate

d) zero

Ans:

Across the plates of a parallel-plate capacitor a constant potential difference is applied. Neglecting any edge effects, the electric field inside the capacitor is constant.
