what is Electric Circuit
Chemical effect of electric current of Class 8
The path of flow of electricity starting from one terminal of cell and returning to the other is called an electrical circuit. It consists of conducting wires and other resistances (like lamps etc.) between the terminals of a battery, along which an electric current flows.
For the flow of electricity, the entire circuit must be made up of conductors. The symbols of commonly used components in the electric circuit are shown in the figure below.
OPEN ELECTRIC CIRCUIT:
An electric circuit through which no electric current flows is known as open electric circuit. The electric circuit will be open circuit if the plug of the key is taken out or if the connecting wire breaks from any point.
An electric circuit through which electric current flows continuously is known as closed circuit.
