Electricity is an energy that runs machines, lights light bulbs and makes heat. Electricity is invisible. There are protons, neutrons, atoms and electrons in electricity. 
A light bulb  works by  electricity flowing through the wire which causes the filament to heat up. The heat makes the filament glow. Resistance is the concept that causes it heat up.
