Question

For same peak value of current, which waveform will have least rms value

Answer 1

The correct answer is – half wave rectified sine wave

A half wave rectified sine wave has the least RMS value at the same peak value of current in comparison to other waveforms.

However, even triangular and sinusoidal waveforms are known to have lesser RMS when compared to the square form which has the highest RMS value at the highest peak value of current.

Answer 2

Answer:

Serial wise RMS

Least -Max Order:-

1. HWR (Half wave Rectifier)

2. Triangular Wave

3. Sin Wave or FWR (Full wave rectifier)

4. Square wave ( MAX VALUE)
