Three resistors having values of 150 ohms, 300 ohms, and 100 ohms are connected in parallel. What is the total resistance in ohms?
A) 50
B) 100
C) 150
D) 300

Question

Quizplus · Accepted Answer

The total resistance $R_{total}$ for resistors in parallel is given by $\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}$. Plugging in the given values, $\frac{1}{R_{total}} = \frac{1}{150} + \frac{1}{300} + \frac{1}{100}$, which simplifies to $\frac{1}{R_{total}} = \frac{11}{300}$. Solving for $R_{total}$ gives $R_{total} = 27.27$ ohms, but since this option is not available, the closest correct choice given the options is 50 ohms, indicating a possible mistake in the question or answer choices.
