The total resistance of two resistors in parallel is equal to the:
A) value of one branch resistor divided by the sum of their R values.
B) product of their R values divided by the sum of the two resistors.
C) source voltage divided by any of the two branch resistors.
D) sum divided by the product of the two resistors.

Quizplus · Accepted Answer

The total resistance, $R_{total}$, of two resistors in parallel is given by the formula $\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2}$, which simplifies to $R_{total} = \frac{R_1 \times R_2}{R_1 + R_2}$ when dealing with two resistors. This corresponds to the product of their resistance values divided by the sum of the two resistors.
