Question
What is the current in a circuit with an applied voltage of 120 volts and a resistance of 80 ohms?
Answer Options
- A) 9600 amperes
- B) 200 amperes
- C) 0.000667 amperes
- D) 1.5 amperes
Correct Answer: D
Explanation
Using the Ohm’s Law formula for current: I = E / R (T5D01).
I = 120\text{ V} / 80\text{ Ohms} = 1.5\text{ Amperes}. This is the current draw you would expect for a load connected to a standard 120\text{ V} wall outlet with 80\text{ Ohms} of resistance.
