What is lightning? Why does wearing rubber shoes help you during a storm?

When flashlight switch on, the terminals of the battery are connected over the light bulb. The connection makes a voltage go over filament in the light bulb. The voltage makes the charge from a side that has the higher electrical potential energy to the side that has the lower electrical potential energy. When the moving charge defeat the resistance, the electrical energy change into other modes of energy, the light. When the electricity go over the tungsten, the filament will issue the light and heat.

Because the rubber shoes can disconnect the electricity, it's a material that isn't easily, hard to let a charge go through is called insulator. Insulator make the electricity more safety, they can keep the charge away from our body.
