Answer:
That an item is neither moving nor staying still in a position that is building up energy.
Explanation:
That's Ampere's Law. ( C ).
The magnetic permeability is the proportionality constant.

The answer is: 120V
Power is the rate at which energy is supplied/transformed in time:
we can write:
V ddp in Volts represents Energy/Charge i.e. energy carried by each coulomb;
I current in Amperes represents Charge/time or coulombs passing each seconds.
combining them we have:
Power = energy/time = V • 1
or
1200 = V ⋅ 10
V = 1200/10 = 120V
