Assume that three resistors, each having a value of 24 ohms, are connected in parallel. What is the total resistance in ohms?
A) 3
B) 8
C) 24
D) 72

Question

Quizplus · Accepted Answer

When resistors are connected in parallel, the total resistance is calculated as: 
1/total resistance = 1/resistor 1 + 1/resistor 2 + 1/resistor 3 + ...
In this case, we have three resistors of equal value:
1/total resistance = 1/24 + 1/24 + 1/24
1/total resistance = 3/24
total resistance = 24/3
total resistance = 8
Therefore, the answer is B) 8.
