Question

What is the effective (rms)current value for an AC current with an amplitude of 14 A?
A) 14 A
B) 7.0 A
C) 9.9 A
D) 3.7 A
E) ​2.6 A

Quizplus · Accepted Answer

The effective (rms) current value for an AC current with an amplitude of A is given by the formula Irms = A/√2. Plugging in A = 14 A, we get Irms = 14/√2 ≈ 9.9 A. Therefore, the correct answer is choice C.
