Question

If 120 V are applied to 100 ohms of resistance, what current will flow?
a. 12000 A
b. 1.2 A
c. 0.83 A

Answer 1

If the resistance is ohmic (follows Ohm's law of V=IR), then current should be
I = V/R, where I is current, V is voltage, and R is resistance.

Current in this case will be
I = (120V)/(100Ω)
I = 1.2A
