Question

Which equations can be used to calculate the electric potential energy stored in a capacitor? Check all that apply. U = QV U = CV U = U = CV2 U = U = QV2

Answer 1

U=1/2QV

U=1/2CV^2

U=Q^2/2C

Answer 2

There are different ways to calculate the electric potential energy stored in a capacitor.
Among these forms we have:
Form 1:
U = (CV ^ 2) / 2
Form 2:
U = (Q ^ 2) / 2C
Form 3:
U = (QV) / 2
Where,
Q: load
C: capacitance
V: voltage.
Answer:
U = (CV ^ 2) / 2
U = (Q ^ 2) / 2C
U = (QV) / 2
