Hair becomes positively charged and the comb becomes negatively charged. The hair will be attracted to the comb and rise in the air because negative and positive charges attract. Lightning is due to a large amount of electric charge moving from one cloud to the next. B. Current Electricity is created. Current electricity is a flow of electrons that is generated by such things as a battery or generator.
Electromotive force is the pressure that pushes an electric current through a circuit.
The electromotive force pushes electrons through an object creating a stream of electrons in one direction. Electrons jump from one atom to the next. Electric energy can move in certain directions creating an electric current. Cars and trains use direct current. Radios and televisions use alternating current and direct current.
