A voltage divider is an essential electrical circuit configuration used to generate a specific voltage output that is a fraction of its input voltage. It consists of two or more resistors connected in series across a voltage source. The voltage is divided between the resistors proportionally to their resistance values, following the principle of Ohm's Law. . This configuration is widely used in electronic circuits to create reference voltages, biasing components, and scaling down voltages for measurement or processing by other circuit elements. The simplicity and reliability of the voltage divider make it a fundamental concept in both analog and digital electronics.
