Potential Divider/Voltage Divider
Potential dividers divide up the voltage within a circuit, so that parts of a circuit only receive the voltage they require. Potential dividers usually consist of two or more resistors arranged in series across a power supply.
Potential Dividers - GCSE Physics Revision
A demonstration of how potential difference (voltage) can be shared out in the ratio of resistances in series circuits. Also how it can be used to alter the voltage across a component in, for example a motor throttle, or to sense a change in environment using a thermistor or an LDR.
