What measurement is typically indicated in volts?

Voltage is the measurement that is typically indicated in volts. It represents the electric potential difference between two points in an electrical circuit. Voltage is crucial because it determines the force that pushes electric charges through a conductor, which is needed for the flow of current.

In practical terms, when measuring or dealing with electrical systems, voltage is what allows you to understand how much electrical potential energy is available to drive the current through a circuit. For instance, household outlets usually supply 120 or 240 volts, depending on the region, and this voltage is what enables appliances to operate.

The other concepts, such as current (measured in amperes), resistance (measured in ohms), and power (measured in watts), are all related to voltage but represent different properties of electrical systems. Current refers to the flow rate of electric charge, resistance measures how much a material opposes that flow, and power quantifies the rate of energy transfer. Each of these measures plays a role in an electrical system's behavior, but voltage specifically refers to the potential difference expressed in volts.
