How to Measure Voltage?

There are several ways to measure voltage that are mentioned below.

Measure Voltage Using Voltmeter

Voltage between two points in a system can be measured by using a Voltmeter. Voltmeter is used to measure the voltage of an Alternating Current (AC) circuits or Direct Current (DC) circuits. The voltmeter connected across the two points measures the voltage drop between them when the current flows through the circuit.

There are two types of Voltmeters are:

• Analog Voltmeter
• Digital Voltmeter

Analog Voltmeter

Analog voltmeters provide continuous readings and are suitable for measuring both AC and DC voltages. Analog voltmeter has a pointer or needle to indicate the voltage on a scale. They have a moving coil or moving iron design. Due to digital voltmeter, these days analog voltmeter is less common usage.

Digital Voltmeter

Digital voltmeter contains voltage readings as numerical values on a digital screen. They are more accurate and easier to read than compared to analog voltmeters. The digital multimeter measures and displays the voltage readings on an LCD screen in the form of digits. The main advantage of using digital voltmeter is we can measure both direct voltage and alternating voltage with the same device just by changing the meter settings such as ac voltage and dc voltage.

Voltage is an important parameter in circuits. It is the potential difference between the two charged points per unit charge in an electric field. In this article, we will discuss about voltage, voltage symbols, voltage units, voltage properties, voltage formulas, and types of voltages. We will also cover how to measure voltage.
