How Electricity Works

How electricity works learn how electricity works with voltage current amps ac dc transformers inductors capacitors resistors and other basic concepts for the basics of electrical and electronic engineering.

How electricity works. An electromagnet is a magnet that can be switched on and off with electricity. Electricity and magnetism are closely related. In this video we learn how electricity works starting from the basics of the free electron in the atom through conductors voltage current resistors led. Electricity powers our world and our bodies.

When the current flows it works like a magnet. These properties work together inside a circuit allowing electricity to move from place to place. Scientists measure voltage in units called volts current in amps and resistance in ohms. When the current stops it goes back to being an ordinary unmagnetized piece of steel.

There are three main properties that make electricity work.
