What is the shortest time taken for a 100 Hz a.c. to change from zero to half its peak value?
(Assuming the current is a sine wave, I correctly calculated that time to reach its peak value from zero is 2.5ms. However for the question given, 1.25ms was marked wrong and the comment "draw the waveform and think about the time in terms of the period" was left. Please help me understand this)
Answer the question.
1. How to generate an AC? Explain.
2. What are the types of alternating current waveforms?
What are the two ways in which an alternating waveform differs from DC?
