Electric Circuit
The closed path along which electric current may flow is called an Electric
Circuit.
The electric circuit has various elements such as the cell, bulb, conducting
wire, ammeter, voltmeter and switch.
The amount of electric current flowing in a circuit is measured by an Ammeter.
The electric potential of a cell can be measured by a Voltmeter.
Closed Circuit:
If there is no break anywhere in the circuit, it is called closed circuit or
complete circuit.
Current flows in a closed circuit.
In a closed circuit, switch is in ON position.
Electrical appliances do work in a closed circuit.
