Voltage Divider The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives. where is the parallel resistance of R 2 and the load resistor R L . For R 1 = Ω, R 2 = Ω, and V 1 = V, the open circuit output voltage would be V out = V If the voltage divider is suppying a load R L = Ω, then the output circuit voltage is V out = V For this circuit, the total power supplied by the power supply is Index DC Circuits

P total = watts and the power delivered to the load resistor R L is P out = watts. The load then receives % of the total power. The voltage divider is a very important basic circuit, and exploring the calculation above with various values can give you insight into a large number of practical circuit applications. One practical consideration is that a larger value of R 2 compared to R 1 will give you a larger output voltage. But if your
