Voltmeter Formula
A multiplier is a resistance connected in series. Its value is determined through the voltage equation. Resistance in a Series Equation is
V = Im × Rse + Vm
Where,
- V = Voltage,
- Im= Full scale current,
- Rse=Resistance in Series, and
- Vm= Full Scale Voltage
Range of Voltmeter
DC Voltmeters have measuring capacities ranging from 10mV to 1000DC. 1V to 1000 V AC is measured by AC voltmeters.
Least Count of Voltmeter (Analog)
The least count of an analog voltmeter depends on its scale and the number of divisions between two consecutive major marks. For example, if there are 100 divisions between 0 and 10 volts, the least count would be 0.1 volts (10 V divided by 100 divisions).

Voltmeter
Voltmeter is a measuring instrument designed to detect the potential difference between two points in an electric or electronic circuit. A voltmeter is commonly used for AC or DC circuits. Specialist voltmeters may also measure Radio Frequency (RF) voltage.
A device’s voltage can be measured using a voltmeter that is connected in parallel to the said device. This arrangement is significant since parallel objects usually tend to have the same potential difference. It is wired in parallel with the circuit, primarily due to similar voltage losses across it. In this article, we will discuss all the topics related to Voltmeter including its diagram, parts, formula, various types, working principle, how to use, etc.
