Question

sketch the following waveforms and deduce the phase shift between them.
1- V=300sin(wt+40)
i= 100sin(wt-10)

Answer 1

Sketch the following waveforms and deduce the phase shift between them.

V=300sin(wt+40)

i= 100sin(wt-10)

These two waves have the same frequency. The phase shift between them:

$$\Delta \varphi = 40 - (-10) = 50 \text{rad} \cong 6 \text{rad} \cong 343{}^\circ$$

50rad $\cong$ 6rad due to period of $2\pi$ rad
