Four 8.0-Ω resistors are connected in parallel.What is their equivalent resistance?
A) 4.0 Ω
B) 0.50 Ω
C) 2.0 Ω
D) 32 Ω

Question

Quizplus · Accepted Answer

When resistors are connected in parallel, the equivalent resistance can be calculated using the formula: 1/Req = 1/R1 + 1/R2 + 1/R3 + 1/R4. In this case, substituting the values, we get 1/Req = 1/8 + 1/8 + 1/8 + 1/8 = 4/8. Simplifying, we get Req = 2.0 Ω. Therefore, the best choice is C) 2.0 Ω.
