______ is measured in volts.

Voltage is the electric potential difference that drives current through a circuit. It’s the push that moves electrons, and it is measured in volts. One volt equals one joule per coulomb. This idea fits with Ohm’s law, V = I × R, which shows how voltage relates to current and resistance. In practical terms, a battery or power supply provides a certain voltage, and a voltmeter reads that voltage. Other quantities have different units: current is measured in amperes, resistance in ohms, and power in watts.
