Question

An average response rectifier type electronic voltmeter has a dc voltage of 20 v applied to it. the meter reading is

Answer 1

Answer is 22.2V

Explanation:

D.C voltage of 20V is applied to an average response rectifier type electronic voltmeter.

Calibration of Rectifier type of instruments is in terms of root mean square values (RMS)

This type of voltmeter will display 1.11 times the average voltage.

Therefore 20* 1.11 = 22.2

Voltmeter will read 22.2 V

Hope it helps
