Electric Current - Definition, Types, Properties, Effects, FAQs

WebIn the functioning of the battery , chemical reactions release electrons which want to move to the cathode but the electrolyte prevents them from doing so. Hence, it move along the circuit . So is it safe to assume that all electrons moving in the circuit are from the battery. If yes , then why do conductors need to have free electrons? • WebA voltage source is a device that provides the force necessary to drive electric current through a circuit. Batteries and generators are examples of voltage sources. Resistor. A resistor is a device that opposes the flow of electric current in a circuit. It is often used to control the amount of current flowing through a circuit. Capacitor WebThey are called "free electrons". This makes them good conductors.
