VHS: How Electricity Works

Hi, I'm Ed Willis, winner of Southern Illinois Electrician of the Year three years running.

Electricity is a powerful natural force, consisting of a flow of electrons, negatively charged particles,

The rate of flow of electrical current is measured in amperes.

Voltage is the electric difference between one charged point and another.

Electricity flows from a higher voltage point to a lower voltage point.

Ohms are the measurement of resistance. An electrical charge often has to be limited...

... to ensure a circuit doesn't burn out.

Here is a basic battery circuit illustrating these principles.

Hopefully, these basics will help you on your electrical journey.

Just remember - don't get shocked!
