for ac networks if the voltage wave form is V=Vm sinwt here the voltage Vm=230 for the frequency 5..

Answer / vikramsenareddy

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
