An alternating current is represented by the equation I = I∫sinπt which of the following equation represents an alternating current of frequency and amplitude twice that of the above current ?
AI = I∫sin(2πt)
BI = 2I∫Sin(2πt)
CI = 2I∫Sin(πt/2)
DI = 2ISinπt
Correct answer
B. I = 2I∫Sin(2πt)
Explanation
I = 2I∫Sin(2πt) is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
