QUESTION:

The circuit in Figure P 11.5-11 consists of a source connected to a load. Suppose the phase angle of the source voltage is doubled so that \(v_1(t)=24 \cos \left(3 t+150^{\circ}\right)\) V. How will the following change?

(a) The impedance of the load

(b) The complex power delivered to the load

(c) The load current

ANSWER:

Step 1 of 4

(a)

If the phase angle of the source voltage is doubled, the impedance of the load will not change since the load impedance depends on the frequency of the source only.
