Voltmeter
EEE
voltmeter measures the potential difference (voltage) between two points in a circuit. It is a high-resistance device connected in parallel with the circuit. In an analog voltmeter, a galvanometer with a series resistor moves a pointer proportional to the measured voltage. In a digital voltmeter, an analog-to-digital converter (ADC) is used to display the voltage reading.
