You'll need to think about charges/electrons moving.
Voltage is the potential difference between two points and = the work done per unit charge between the two points.
Power is just the amount of work done per unit time. So P = Wd/t and V = Wd/Q
So Wd = VQ and Wd = Pt
so VQ = Pt
VQ/t = P
but Q/t = I
so VI = P
P = IV
Hope this helped, It's not super in depth but it depends if you need to know more about quantities such as the Work Done
