Alternating CurrentHard
Question
An AC voltage is given by :
E = E0 sin
Then the mean value of voltage calculated over time interval of T/2 seconds :
E = E0 sin
Then the mean value of voltage calculated over time interval of T/2 seconds :
Options
A.is always zero
B.is never zero
C.is (2e0/π) always
D.may be zero
Solution
If net area of E − t curve is zero for given inteval then average value will be zero.
