What is Electric voltage? (Definition, Formula, Volt, and Voltmeter) Introduction

In this article, you will know what is voltage or electric voltage and the unit of voltage that is a volt. We will also discuss ac voltage, dc voltage, or ac dc voltage and actually, voltage is a high voltage or low voltage.

We will also define some related terms which are, common mode voltage, RMS voltage, voltmeter, and use of a voltmeter.

If you're like most people, the word "voltage" probably doesn't mean much to you. But if you're an electrician or an engineer, it's a very important concept.

Voltage is said to be the difference in electric potential between two points. In other words, it's the force that drives electrons from one point to another. Without voltage, there would be no electricity. So next time you flip on a light switch or plug in your laptop, remember voltage!

What is voltage?

Voltage, electric potential difference, electromotive force, or “pressure” is the difference in electric potential between two points. The voltage between two points is measured in volts (V).

Voltage can be found in many places; for example, a common 9-volt battery has a voltage of 9 volts. A 120-volt wall outlet has a voltage of 120 volts. An electrocardiogram (EKG or ECG) measures the voltage between two electrodes placed on the skin.

In an electric circuit, voltage provides the force that pushes electrons through the wires and around the circuit. The amount of voltage in a circuit is determined by the type of battery or power source being used.

Short Definitions ·        It is the difference of potential between two-point charges that’s why it is also called Potential difference.

·        The force or pressure required for the flow of charges is called voltage.

·         It is the force required for the motion of electrons, so it is also called Electro-Motive Force.

The history of voltage

In the field of electrical engineering, voltage, electric potential difference, electric pressure or electric tension (but more commonly just voltage) is the difference in electric potential energy between two points per unit charge.
