Because θ =wt.

Ajit said:   4 years ago
How wt is equal to 250? Please explain.

Sam said:   7 years ago
Formula = Io sin2^ft.
F = 250/2.
= 6sin 250,
= 5.638 = -5.64,

The instantaneous values of a sinusoidal waveform is given as:

Vi = Vmax Sin θ.
= 6 Sin 250°
= 6(-.94).
= -5.64 V.

Please give the answer.

V = Vmax*Sin(wt).

Where wt is angular frequency in this case is 250 so,
V = 6 * sin(250).

Therefore V = -5.64.

According to the formula, let

V [instantaneous] = V[peak]sin[wt].

6*sin[256].

6*-0.097.

-5.64.

V=Vm Sin wt so, V=6,wt=250
V=6 sin250
V=-5.64v
