The maximum voltage of an ac signal is 8.0 V. What is the rms value of this voltage?
A) 2.8 V
B) 5.7 V
C) 6.2 V
D) 4.0 V
E) 16.0 V

Question

Quizplus · Accepted Answer

To find the rms value of an ac signal, we need to divide the maximum voltage by the square root of 2 (approximately 1.414). 
So, rms value = (maximum voltage) / (square root of 2) 
= 8.0 V / 1.414 
= 5.7 V.
Therefore, the best choice is B.

The Maximum Voltage of an Ac Signal Is 8
