Definition:
Voltage, also known as electric potential difference, is the measure of electrical energy between two points in a circuit. It represents the force that pushes electric current through a conductor, such as a wire.
Measured in: Volts (V)
Explanation:
Voltage is often compared to water pressure in a pipe—it’s what drives the flow of electricity. The higher the voltage, the greater the potential energy available to move electrons through a circuit. It’s essential for powering devices, from small electronics to large HVAC systems.
Example:
A standard household outlet in the U.S. typically supplies 120 volts, while large appliances like air conditioners may require 240 volts for proper operation.
