1 Manually adjustable, variable, electrical resistor. It has a resistance element that is attached to the circuit by three contacts, or terminals. The ends of the resistance element are attached to two input voltage conductors of the circuit, and the third

an electrical device for dividing a DC or AC voltage into parts. All voltage dividers consist of reactances or effective resistances.
Voltage dividers are usually used to measure voltage. At low voltages series-connected resistors (Figure l,a) are used.
Capacitive voltage dividers with fixed or variable capacitors (Figure l,b), as well as induction voltage dividers (Figure l,c), are used for alternating currents. Capacitive voltage dividers, which consist of several series-connected high-accuracy capacitors (Figure 2), are used in electric power
engineering to take off small amounts of power from a high-voltage transmission line (up to 500 kilovolts). An autotransformer is an example of an inductive voltage divider.
