for ac networks if the voltage wave form is V=Vm sinwt here
the voltage Vm=230 for the frequency 50hz then the time
period is 0.02 sec then for the time period 0.12 sec what
is the voltage

Answer Posted / anwar khan
If 0.02 second is one cycle 0.12 is 6 cycle. After 6th cycle
the voltage will be zero.
Mathematically 50hz = 1/50 sec = 0.02 Sec = Sin(2pi) radians.=0
Or Sin 360 (degrees) = 0
w = 2pi in radians = 360 in degrees.
