This is the basis of generation in rotating machines. You can produce a current in a conductor by connecting opposite ends to the + and-poles of a battery, but don't try this with your car battery or you will burn out the conductor and produce a lot of heat. It is safer to use a small dry battery.
Electric current is a flow of electric charge (usually in the form of electrons) through a substance. The substance or conductor that an electric current flows through is often metal wire, although current can also flow through some gases, liquids, and other materials.Circuits can be wired in two ways.In a series circuit, current flows to each bulb in turn. Both bulbs are dimly lit.he substance or conductor that an electric current flows through is often metal wire, although current can also flow through some gases, liquids, and other materials.
