Q1:

A periodic voltage has following value for equal time intervals changing suddenly from one value to next... 0, 5, 10, 20, 50, 60, 50, 20, 10, 5, 0, -5, -10 etc. Then rms value of the waveform is

A 31 V

B 32 V

C insufficient data

D none of these

ANS:A - 31 V

RMS value = 965 = 31.064 Volt.
