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.
Here, Vo = Output Voltage.
Vs = Source Voltage.
Rl = Load Resistance.
Rs = Source Resistance.
Vo = 120*470/(12+470).
= 117 Volts.

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

Vl=Rl*Vs/(Ri+Rl)
VL=470*120/(12+470)
Vl=117v
VL=470*120/(12+470)
Vl=117v
