What is the voltage drop across a 2-ohm resistor used in a 12-volt series circuit that is flowing 1.5 amps?
A) 3 volts
B) 9 volts
C) 12 volts
D) 1.5 volts

Question

Quizplus · Accepted Answer

The voltage drop across a resistor in a circuit can be calculated using Ohm's Law, V = IR, where V is the voltage across the resistor, I is the current through the resistor, and R is the resistance. For a 2-ohm resistor with 1.5 amps flowing through it, the voltage drop is V = (1.5 amps) * (2 ohms) = 3 volts.
