What Is Electrical Voltage

What Is Electrical Voltage? Voltage Explained In Detail

How do you define electrical Voltage? Well, Voltage refers to the amount of electrical pressure present within an electric circuit.

Voltage is an electrical term and a measurement of energy in an electric circuit, which searches to push electric charge around a circuit. In short electrical Voltage is electrical pressure.

So we can tell, Voltage is the potential difference between two points. It’s an indirect measure of the work done to move a charge from one point to another.

Electrical Voltage Explained

Voltage or potential difference is a difference of positive and negative electrical potential between two points. Voltage is measured in volts (V). Electrical Voltage also can be defined as the ability to induce an electric current through a conductor such as a wire.

Voltage is the energy (potential) per charge. The symbol for Voltage is V. Electrical voltage is a difference in electric potential between two points. It’s measured in volts, designated as V.

Voltage can be defined by an equation such as V, or E=IR, referring to the electrical energy produced between two points if a constant current of 1 ampere flows through them for 1 second.

Electrical Voltage Explained

Voltage is often confused with electrical pressure or electric tension. But Voltage differs from these terms because it compares differences in energy instead of directly comparing electric charges as pressure does.

Electrical Voltage Invention

Electricity can be traced back to the 1600s when a scientist named Francis Bacon began experimenting with electric charges. Through his experimentation, he discovered that rubbing fur with amber attracted small pieces of paper.

He also found that they produced an electric charge when he rubbed certain materials together. This laid the foundation for modern electrical experiments and helped develop many inventions such as the telegraph, the telephone, the radio, television, and the computer, to name a few.


Electrical Voltage is the measurement of the electric potential or difference in electrical potential between two points. Voltage units are based on the amount of charge (electrons) that move from one point to another.

How much Voltage is actually behind a lamp when you flip the switch on a lamp? Why do some plug-in items require different voltage levels?

With electrical Voltage, many things that can be confusing become logical once you understand the formula. This article will explain what the formula’s components mean and which units it should be measured in.
