Question

How does the potential difference change with the effect of the dielectric when the battery remains connected across the capacitor?

(a) Increases

(b) Decreases

(c) Remains constant

(d) Becomes zero

This question was addressed to me during an interview for a job.

The query is from Effect of Dielectric on Capacitance in division Electrostatic Potential and Capacitance of Physics – Class 12

Answer 1

The correct answer is (c) Remains constant

Best explanation: As the battery remains connected across the capacitor, so the potential difference remains constant at V0 even after the introduction of the dielectric slab. In this way, dielectric has an effect on potential difference.
