Electrical potential is measured in which unit?

Watts
Amperes
Pascals
Volts

The correct answer is: Volts

Electrical potential is measured in volts, which is the correct answer. The term "voltage" refers to the potential difference between two points in an electrical circuit, quantifying the amount of energy per unit charge that is available to drive electric current. Essentially, 1 volt is defined as the potential difference that will drive 1 ampere of current against 1 ohm of resistance. This unit is foundational for understanding electrical circuits and power systems, making it crucial for gas fitters who often work with gas appliances that may also involve electrical components. The other options reflect different measurements: watts measure electrical power, which combines both voltage and current; amperes quantify the flow of electric current; and pascals measure pressure, unrelated to electrical potential. By understanding that electrical potential specifically refers to voltage, you can better grasp concepts related to both electricity and its applications in gas fitting scenarios.
