The values of alternating voltage and current in a circuit connected to a 50 Hz supply are 400 V and 20 A respectively and these quantities are sinusoidal. At t = 0, the instantaneous values of both positively rising voltage and current are 283 V and 10 A, respectively. Choose the expression for the voltage at time t.
1
v = 400 sin (100 π t + π/6)
2
v = 283 sin (100 π t + π/6)
3
v = 283 sin (100 π t + π/4)
4
v = 400 sin (100 π t + π/4)
