Electricity

What is electricity?

Electricity is the flow of electrical charge.  Its an energy carrier, so it gets it is energy from other sources of energy.  The nucleus contains protons and neutrons.  Electrons surround the nucleus.  When there is a balancing force between protons and electrons, they can gain or lose an electron.  When an electron is lost, an electric current develops, which then electricity can be developed.

Why is electricity important?

Electricity is used in almost everything we do! Our society and the way that we live our lives today wouldn’t be able to function without electricity. Our phones, our laptops the two things that we use most these days would not be able to function without electricity. It is an essential to our lives today.

What is electric current?

Electric current is electricity flowing through a conductor.  The flow of electricity creates a current, which is measured in amperes. It is flow of electric charges through a surface at the rate of one coulomb per second. I=Q/t (Q=charge t=time)

What is resistance?

Resistance is the hindrance to a flow of charge through wires and external circuits.  Through the course of the electrons flow, they come across a delay in their movement, which is the resistance.  More collisions or stopping points in the movement of the electrons means there is more resistance.
