A full wave rectifier type meter is used to measure the wave shape shown in figure. The voltmeter is calibrated to read rms value of sine wave. The reading of voltmeter will be
100 V
111 V
Answer: Option
Explanation:
Peak value of sine wave = 100 x 1.11 = 111 V.

After rectifier, the voltage is a DC of value 100V. Would why its peak to be detected?
The RMS value of the dc same as its voltage (Being DC) and the meter reads RMS value itself. So, the answer will be 100V.
