Chapter 9, Problem 84P

a.

To determine

Find the values of $V_l$ and $V_s$.

b.

To determine

Draw the phasor diagram for $V_s,V_l\text{and}{V}_{\text{L}}$.

c.

To determine

How much amplitude of $V_s$ must be increased to maintain the load voltage to 120 V for $R_{\text{L}}=2.5\Omega \text{and}{X}_{\text{L}}=j4\Omega$.

d.

To determine

How much amplitude of $V_s$ must be increased to maintain the load voltage to 120 V for $R_{\text{L}}=2.5\Omega \text{and}{X}_{\text{L}}=j4\Omega$ and capacitive reactance of $-j2\Omega$ connected across the load terminals.
