Question

Calculate the electric potential energy in a capacitor that stores 9.40 10-10 C of charge at 50.0 V. Use .

Answer 1

Given, charge stored, Q= 9.40 ×10⁻¹⁰ C

Voltage, V= 50.0 V

Electric potential energy of a capacitor is given by,

U=$\frac{1}{2}QV$

Substituting the values,

U=$\frac{1}{2}(9.40*10^{-10})(50)$

=235×10⁻¹⁰ J

∴The energy stored in the capacitor is 235×10⁻¹⁰ J.
