VOLTAGE-DIVIDER CIRCUITS

A very important type of electronic circuit is the voltage-divider circuit. This type of circuit in its simplest form consists of two or more resistors connected in series with a power source. A voltage-divider circuit allows one to obtain several different voltages from one power source simply by means of changing values of resistance. Such circuits are used extensively in electronic equipment. The power-supply system of a transistor radio is a good example of a system that uses voltage-divider circuits to obtain various voltages to operate the radio circuitry.
