A 470 RL is connected across a voltage source, VS, of 120 V. The source's internal resistance, RS, is 12 . What is the output voltage across the load?

[A]. 120 V
[B]. 0 V
[C]. 117 V
[D]. 12 V

Answer: Option C

Vl=Rl*Vs/(Ri+Rl)

VL=470*120/(12+470)

Vl=117v

vl = 470*120/ (12+470) = 11.7v.

Output Voltage Vo = Vs*Rl/(Rs+Rl).

Here, Vo = Output Voltage.

Vs = Source Voltage.
Rl = Load Resistance.
Rs = Source Resistance.

Vo = 120*470/(12+470).

= 117 Volts.
