Furthermore, an electric circuit provide the complete data needed for various electrical jobs like troubleshooting and repairing electrical appliances, conducting actual electrical wiring jobs, and planning and designing building and residential wiring installation. To develop the required skills for these jobs, one must first master the art of interpreting electric circuits.
There are three types of electric circuits. One type is the series circuit where the loads are always connected end to end. The parts and components of the circuit (i.e., the bulb and the switch) are said to be in series with the source circuit. Another type is the parallel circuit. In this type, the loads are connected across the line circuit. There are two more separate parts in the circuit that are fed by another source voltage. The third type is a combination of series and parallel circuits.
