Voltmeter works on the principle of Ohm's rule.
Explanation:
Voltmeter is a device used to calculate electrical potential or voltage. Voltmeter is based on the Ohm rule principle, which says that the resistance voltage is directly proportional to the current flowing through it. In order to apply this in real time, we are constructing a galvanometer so that the coil is suspended in a magnetic field. We realize that the current passing through the circuit always flows through the coil and the needle connected to the coil, which travels around the reading scale, so that the movement of the needle is directly related to the current moving through it.
