CBSE Class 12-science Answered
The value of instantaneous voltage received from a.c. source is given by following equation, V = 200-?2 sin 314t volt, then find the root mean square value of the source?

Expert Answer
Instantaneous voltage of ac source = ( 200-√2) sin(314 t ) V
Maximum voltage = ( 200-√2) V
Root mean square value of voltage = [ ( 200 -√2) / √2 ] V = 140 V
