Question

expression for energy stored in a capacitor in terms of charge and capacitance ​

Answer 1

Energy stored in the capacitor is given by Expression U=CV2/2 1

if you wanna find out it in terms of charge and capacitance then put the value of V

As Q=CV

V=Q/C

Put this value in eq 1

U=CQ^2/2C^2

U=Q^2/2C
