Question

How does electric current flow in a circuit?

Answer 1

Hint: Electrical current always flows in a loop which is used to power lamps or other electrical components. The loop is called an electric circuit. A circuit consists of different components connected together by the wires .A power source such as the battery pushes the current around the circuit.

Complete answer:
In order to know how current flows in the circuit first let’s know what is current.
Electric current is a stream of the electrical charge through a material usually in the form of the electrons.
Usually metal wire is a substance which is used as a conductor for the flow of the current.
Now let’s know when current flows in a circuit.
When there is no gap in the loop, the current only flows when a circuit is complete.
In a closed loop or closed circuit the electrons flow through the connecting wires and parts such as lamps from the negative terminal or connection to the power source and back to the positive terminal.
Now let’s know how current flows in a circuit.
Electrons flow from the negative to the positive when a wire is attached to the terminal of the battery.
Unlike attracting charges such as repelling the same charges, they are repelled from the negative and drawn to the positive and we know that electrons have the negative charge.
So this is how current flows in a closed circuit.

Note:
As an approach to solve this question first we know what is current and then we tend to know that current only flows when circuit is closed and it will flow from the negative terminal to the positive terminal when connected to the battery.
