Note: Variations of potential divider are – rheostat, variable resistor, and/or potentiometer.
A Voltage-Divider enables you to obtain any voltage up to the maximum of the supply e. m. f solely by means of changes to resistors values.
- A Voltage Divider finds application when you need a fraction of supply voltage to power a circuit; an example is in resistors array taping in multimeter
- It finds useful applications in transistor circuits to stabilize the operating of a transistor or biasing to determine the operating point.
- Potential Divider simply allow you to tap estimated voltage value from any or combination of resistors and ground potential
- Variable Resistor, Preset/Rheostat, or Potentiometer enables you to derive smooth voltage increment or decrement between supply and ground.
Typical Areas of use of Voltage-Divider:
- Photo Diode: in circuits for Street Lights control
- Variable Resistor: Dimmer Switch; Volume Control; Shower Temperature
