Electric Switch Diagram Class 6. An electric bulb has a filament that is connected to its terminals. 14 9 a and when we close an electric circuit an electric current flows through it fig.
Electrical appliances such as table fans electric lamps washing machines juicers and mixers radio tv mobiles torch and electric toys have in built switches. An electric bulb glows when electric current passes through it. The black wire power in source attaches to one of the switch screw terminals.
The electrical wiring adds additional wiring to the same principles of 3 way switching.
There is an air gap between the connecting wires so the circuit is not complete and therefore the bulb will not glow. Electric torch a schematic diagram of an electric torch is shown in fig. In a closed electric circuit the electric current passes from one terminal of the electric cell to the other terminal. When we open an electric circuit the flow of electric current in the circuit stops fig.
