Determine the rate at which the electric field changes between the round plates of a capacitor, 5.8 cm in diameter, if the plates are spaced 1.2 mm apart and the voltage across them is changing at a rate of 150 V/s.

The rate at which the electric field changes between the round plates of a capacitor is .

Explanation:

It is given in the problem that the round plates of a capacitor are spaced some distance apart and the voltage across them is changing.

The expression for the electric field in terms of voltage is as follows;

Here, E is the electric field, V is the voltage and d is the distance of separation.

Differentiate expression of the electric field with respect to time, t.

Convert the distance of separation from mm to m.

d= 1.2 mm

Calculate the rate at which the electric field changes.

Put and

Therefore, the rate at which the electric field changes is .

i believe the answer is electric potential.
