300 ohms = I x 120 volts: I = 120 volts / 300 ohms: I = 0.4 amps
The correct answer is: 0.4 amps
Using Ohm's Law in the form V (volts) = I (amps) x R (ohms), complete the following task: In a circuit with an initial voltage of 120 and 4 different devices (load) totaling 300 ohms, what is the amperage involved? Which of the following correctly answers the question?
300 ohms = A x 120 volts: A = 300 ohms/120 volts: A = 2.5 amps
120 volts = I x 300 ohms: I = 120 volts/300 ohms: I = 0.4 amps
I = 300 volts/120 ohms: I = 2.5 amps
R = 300 ohms x 120 volts: R = 36,000 amps
