A battery or generator produces voltage -- the force that drives current through the circuit. Take the simple case of an electric light. Two wires connect to the light. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out.he blood vessels carry the flow of blood through your body. The wires in a circuit carry the electric current to various parts of an electrical or electronic system. Your heart is the pump that drives the blood circulation in the body.
Your birth tree is Lime Tree, the Doubt Accepts what life dishes out in a composed way, hates fighting, stress and labour, tends to laziness and idleness, soft and relenting, makes sacrifices for friends, many talents but not tenacious enough to make them blossom, often wailing and complaining, very jealous, loyal.
