Types of Current
Electric Circuits
Current flows from a battery (power source) to an electric component. The component converts the electric energy into another type of energy. A light bulb is a component that converts electrical energy into light and heat energy.
Electrostatic Charges
Charging by Contact (friction)
Objects can be charged by rubbing them. When a polythene rod is rubbed with a woolen cloth, electrons move from the cloth onto the polythene rod.
