Let’s talk about the basics of power.
The rate at which you work is power.
Work (W)=force(F)*distance(D)
Power(P)=work/Time
The following is an overview of electrical engineering
Voltage (V) refers to the amount of work required to transfer a unit charge from one place to another.
V=W/q(charge)
We know that Current(I), is the rate of charge flow ie.
current(I)=charge(q)/time(t)
Also, you can see the equation above.
