Question

In the circuit shown below, if the source voltage $V_s=100\angle {53.13}^{o}V$ then the Thevenin's equivalent voltage in Volts as seen by the load resistance $R_L$ is

• A. $100\angle {90}^{o}V$
• B. $800\angle 0^{o}V$
• C. $800\angle {90}^{o}V$
• D. $100\angle {60}^{o}V$

Answer 1

The correct option is C $800\angle {90}^{o}V$




$V_{L_1}=\left(\frac{j4}{3+j5}\right)100\angle {53.13}^o$

$=80\angle {90}^{o}V$

$V_{th}=10V_{L_1}=800\angle {90}^{o}V$
