I (current) = v (voltage) / r (resistance)
I = 120v / 28ï = 4.285 amperes = 4.29 amps
FYI: Ohm's Law shows the relationship between voltage, current, and resistance. This equation, i = v/r, tells us that the current, i (in amps) flowing through a circuit is inversely proportional to the resistance, r (in ohms), but current is directly proportional to the voltage, v (in volts).
