Question

what is the formula of potential diffrence

Answer 1

The potential difference between points A and B, VB − VA, defined to be the change in potential energy of a charge q moved from A to B, is equal to the change in potential energy divided by the charge, Potential difference is commonly called voltage, represented by the symbol ΔV: ΔV=ΔPEq Δ V = Δ PE q and ΔPE = qΔV.

• $\underline{\boxed{\sf V = W / t}}$

here,

• V = potential difference
• W = Work done
• t = time taken

by ohm's law

• $\underline{\boxed{\sf V = I × R}}$

here,

• V = potential difference
• I = current
• R = resistance
