Measuring DC voltage accurately is a fundamental skill for electricians, electronics hobbyists, and anyone working with electrical systems. A multimeter is the most common tool used to measure DC voltage, and it is a versatile tool that can also measure AC voltage, current, and resistance.
To measure DC voltage, first set the multimeter to the DC voltage setting. Then, connect the black test lead to the negative terminal of the circuit and the red test lead to the positive terminal. The multimeter will then display the DC voltage in volts.
