Q. Assertion : The potential difference between the two conductors of a capacitor is small
Reason : A capacitor is so configured that it confines the electric field lines within a small region of space

 2956  200 Electrostatic Potential and Capacitance Report Error

Solution:

Even, though field may have considerable strength, the potential difference between the two conductors of a capacitor is small because the field lines are confined within a small region of space
