Answer: An electric circuit is a representation of how current moves from the source of the current( example a battery or a cell) through resistors and other devices before entering the source.
Explanation:
The two important types of electrical circuit includes:
--> open circuit and
--> closed circuit.
A circuit is said to be open when the electrical source, such as the battery or the cell, is not connected to any external conductor (or resistance). In this situation, any voltmeter connected across the terminal of the cell measures the total driving force of the cell.
In this type of circuit, current cannot flow from one end of power source to the other due to interruptions.
A circuit is said to be closed if the source of electricity is connected to an external conductor through which current is passed.
In a closed circuit, there is complete electrical connection which allows current to flow or circulate. Here, part of the total driving force of the source is used to drive current through the external resistance and the difference is used to overcome the internal resistance of the battery.
