A series circuit has a 12-volt power source and two resistors of 1 ohm and 2 ohms respectively.How many amps will flow when the circuit is closed?
A) 4 amps
B) 3 amps
C) 6 amps
D) 15 amps

Question

Quizplus · Accepted Answer

The total resistance in the series circuit is 1 ohm + 2 ohms = 3 ohms. Using Ohm's law (V = IR), where V = 12 volts and R = 3 ohms, the current I = V/R = 12/3 = 4 amps.
