To measure electrical potential, you should use a?

To measure electrical potential, commonly referred to as voltage, the appropriate instrument to use is a voltmeter. A voltmeter is specifically designed to measure the difference in electric potential between two points in a circuit. When placed in parallel with the two points of interest, it provides an accurate reading of the voltage.

While a multimeter can also measure voltage, it serves multiple functions, including measuring current and resistance. This versatility makes the multimeter a useful tool in electrical measurements, but for the specific task of measuring electrical potential, a dedicated voltmeter is the direct answer. Other instruments like the ammeter and ohmmeter have distinct roles; an ammeter measures current, while an ohmmeter evaluates resistance.
