Job of a resistor
WebThe principal job of a resistor within an electrical or electronic circuit is to “resist” , regulate or to set the flow of electrons (current) through them by using the type of conductive material from which they are composed. WebThe main job of a resistor is the reduction of current flow and the lowering of voltage in a specific section of the circuit. It is composed of copper wires wrapped around a ceramic rod and coated with insulating paint. They are universally accepted elements of electrical networks and electronic circuits, and their existence is ubiquitous.
