Question

The resistor in the parallel circuit shown both have values of 4 Ω ( ohms). The battery has a value of 12 volts. What's the total circuit resistance?
A. 3 Ω
B. 6 Ω
C. 4 Ω
D. 2 Ω

Answer 1

The equivalent resistance of the circuit is given by:

D. 2 Ω

How to find the equivalent resistance of a circuit?

• If the resistors are in series, the resistances are added.

• If two resistors are in parallel, the equivalent resistance is the product of the resistances divided by the sum.

In this problem, there are two resistors in parallel, with resistances of 4 Ω, hence:

Req = 4 x 4/(4 + 4) = 16/8 = 2 ohms.

Hence option D is correct.
