Topic: Network Theory
A particular current is made up of two components: a 10 A dc and a sinusoidal current of peak value of 1.414 A. The average value of the resultant current is
- A. zero
- B. 24.14 A
- C. 10 A
- D. 14.14 A
Answer: C. 10 A
Explanation: The resultant current is i(t) = 10 + 1.414*sin(wt). The average value of a pure sinusoidal wave over a full cycle is zero. Therefore, the average value of the resultant current is simply the DC component, which is 10 A.
