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

How will you utilise electrical power? You can start from the generating station.
when an induction motor runs on load.at that time if we reduce the supply voltage the current increases.But when it runs without load,if we reduce the supply voltage the current also reduced.why?.i checked it practically also.
