Question

Consider the AC circuit below.

f(t) = 10 cos(t) V
R = 2 Ω
L = 1 H
Vs = 20 V ∠ 7°

(1) Find the voltage v(t).

Answer 1

The voltage v(t) can be found using the formula v(t) = Vo sin(wt). In this case, Vo = 10 V and w = 1 rad/s. So the voltage v(t) is 10 sin(t) VR.

Step-by-step explanation:

The voltage v(t) can be found using the formula v(t) = Vo sin(wt), where Vo is the peak voltage and w is the angular velocity. In this case, Vo = 10 V and w = 1 rad/s. Substituting these values into the formula, we have v(t) = 10 sin(t) VR. So the voltage v(t) is 10 sin(t) VR.
