Electrical Currents
Do you think that electricity is an important factor in our lives? ... An Electrical current is a flow of electric charge along a wire. ... There are two different types of electrical currents, which are Direct Current and Alternating Current. ... Direct electrical currents only flows in one direction. In a direct electrical current circuit, electrons move from the negative pole to the positive pole. ... In a battery, the chemical energy is converted into electrical energy. ... When the two battery terminals are connected together, it allows electrons to move from the negative terminal to the positive terminal to balance the electrical charge. ...
Compared to a direct electrical current, alternating electrical currents change their flow of direction.
