Question

The equivalent resistance (Req) of resistors R1, R2, and R3 connected in series is given by which formula?
Options
A R<sub>eq</sub> = (1/R<sub>1</sub> + 1/R<sub>2</sub> + 1/R<sub>3</sub>)<sup>-1</sup>
B R<sub>eq</sub> = R<sub>1</sub> + R<sub>2</sub> + R<sub>3</sub>
Correct Answer
C R<sub>eq</sub> = R<sub>1</sub>R<sub>2</sub>R<sub>3</sub>
D R<sub>eq</sub> = (R<sub>1</sub> + R<sub>2</sub> + R<sub>3</sub>)/3
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 7 states that "The equivalent resistance of a series combination is the sum of the individual resistances: Req = R1 + R2 + R3 + ..."

Hint

For series resistors, resistances simply add up.
