A potential divider circuit can be used to divide the potential difference to any value up to the maximum provided by the power source.A potential divider circuit consists of two resistors in series.The ratio of potential differences across the resistor is the same as the ratio of their resistances.
If a circuit is connected across one of the resistors the circuit will be supplied with the potential difference across that resistor.
