Description

Voltmeter is an instrument to measure the voltage in the circuit, its role is to measure the potential difference in the circuit, that is, the voltage. Voltage is an important parameter in the circuit, which determines the direction and speed of the electrons in the circuit, and also determines the power and energy conversion efficiency in the circuit. Therefore, voltage measurement is very important for circuit design, debugging and maintenance.
