Explanation of question 7

A circuit takes a current of 14.14A r.m.s. and 20A peak. The current waveform will be

  1. triangular
  2. sinusoidal
  3. rectangular
  4. positive pulses

The answer is :- 2 

For a sinusoidal waveform the rms current value will be 0.707 x peak value, as in this case, therefore the waveform must be sinusoidal.
