Electric Circuit and Components

An electrical circuit or electrical network is a pre-determined pathway to make the electrons flow in the desired direction. The flow of electrons will set up a current flow in the circuit. Normally, the flow of electrical current is opposite to the flow of electrons. An electron is a fundamental sub-atomic particle of an atom possessing a negative charge. To initiate the flow of current and achieve the desired output, the electrical circuit should necessarily be composed of closed pathways. The pathways are made-up of good conductors of electricity such as aluminium and copper.
