What Is a Voltmeter?
A voltmeter or voltage meter is an appliance used for measuring the voltage of a point to another in any electronic circuit. Normally, volts are used for AC circuits or DC circuit. Alternatively, RF voltage can also be measured using specialised voltmeters.A voltmeter is used to measure voltage usually marked in volts, millivolt (0.001volts) or kilovolts 1(k),ooo Volt).
Voltmeter also has a very high internal resistance. This is done principally since it measures the amount of variation in potential difference between two points across a circuit. As a result, the measuring device’s current remains constant. Basically, a high resistance voltmeter would hinder the flow of current through it. This enables the device to make proper voltage readings.
Voltmeter Symbol
The symbol for the voltmeter is typically V, and it includes a circle that touches two terminals.
A voltmeter has the least count for 0.1 V Voltmeter determines accuracy of voltage measurements The unit used by a scientist or an engineer to measure physical quantities on a continuous scale is called as measurement.
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.
