How Electricity Works

Duration: 2 hours

There are many definitions of electricity, each depending on context. A physicist might define electricity as charged particles, protons and electrons, with no reference to movement. A science teacher might define electricity as the flow of negatively charged particles moving through a wire.
An engineer might define electricity as the motion of electrical energy, where electrical energy is defined as the flow of charged particles. The only constant between definitions is that electricity involves charge. In this course, you will learn about the nature and application of electricity.
