Question

A particular electric current is made up of two component: a 10 A and a sine wave of peak value 14.14 A. The average value of electric current is __________

(a) 0

(b) 24.14 A

(c) 10 A

(d) 14.14 A

I got this question in final exam.

Question is from Advanced Problems on Network Theorems topic in portion Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct answer is (c) 10 A

The best I can explain: Average dc electric current = 10 A

Average ac electric current = 0 A as it is alternating in nature.

Average electric current = 10 + 0 = 10 A.
