Question

an alternating voltage v, has a periodic time of 0.01 s and a peak value of 40 volts. when time t is zero v=-20V. Express the instantaneous volyage in the form v=Vmsin(​

Answer 1

Answer:The instantaneous values of a sinusoidal waveform is given as the “Instantaneous value = Maximum value x sin θ ” and this is generalized by the formula. Where, Vmax is the maximum voltage induced in the coil and θ = ωt, is the rotational angle of the coil with respect to time.
