Voltage Divider Calculator For DC Circuits
Voltage dividers are electric circuits used to scale down a voltage by a given fraction. The output voltage of the circuit is proportional to the input voltage (source voltage), but smaller. The circuit divides the source voltage into two parts. Generally, the output voltage of the divider is used to drive another circuit (load). Alternatively, this output can be used as a reference voltage.
The output voltage for this circuit can be found with the following equation:
This calculator assumes there is no load on this circuit. If you need to calculate the voltage out for a circuit with load then use the Voltage Divider Calculator For DC Circuits With Load
