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

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.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
