               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.
