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
Answers were Sorted based on User's Feedback
Ans:
Vm=230
F =50
t =0.12
pie=180
v=?
v= vm sin(2Pieft)
v= 230 sin(2*180*50*0.12) v

Answer / neha
v = Vm sin(2*pie/T)*t
Here,
T=TIME PERIOD=0.12 SEC
therefore,
v= Vm sin(2*pie/0.12)*t

Answer / 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.

Answer / ashish
v = Vm sinwt
after .02 sec.( after one cycle)
v = Vm sin (2*pie*t)= 0 volt
after .02*6=.12 sec.
v=Vm sin(12*pie*t) =0 volt
