Question

A 23pf capacitor is connected to 50v battery how much electrical energy stored in the capacitor

Answer 1

A 12 pf capacitor is connected to a 50 V battery how much electro static energy is stored in the capacitor

The energy stored in a capacitor is electrostatic potential energy and it is related to the charge and voltage of the capacitor plates. Where, C is the capacitance of the capacitor and V is the voltage applied on the capacitor. So, the energy stored in the capacitor is 3×10−9J.
