In `A.C` source peak value of `A.C` is the maximum value of current in either direction of the cycle. Root moon square `(RMS)` is also defined as the direct current which produces the same heating effect in a resistors as the actual `A.C`
Average voltage for the given source is

A

`V_(0)`

B

`2V_(0)`

C

`(V_(0))/(2)`

D

`(3V_(0))/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C

`V_(av) = ("Area of the graph for time" t = 0 "to" T)/("Time interval")`
`V_(av) = ((1)/(2) xx (T)/(2) xx 2V_(0) + 0)/(T) = (V_(0) T)/(2T) = (V_(0))/(2)`
