The path along which electric current flows is called:
A. electric circuit
B. insulator
C. conductor
D. resistor

Hint: In the given options, 2 options allow the flow of current through them, while one doesn’t allow current and the other resists the flow of current. Hence we must find the correct option from the conductor of electric current.

Complete step by step answer:
We know that flow of charges through a conductor or conducting material is called current. Here since, it says the path along which electric current flows, it must definitely be an electric circuit. Whereas, insulators and conductors are material which either doesn’t allow or allows the flow of current through them. While the resistor is an electrical component, which resists the flow of charges.
An electronic circuit consists of a source, a load like a resistor or a capacitor or lamp, and a few connecting wires. Other electronic components include a transistor or integrated circuits and microprocessors. These can be represented on a paper symbolically. These are called circuit diagrams. They also indicate the direction of current in them. In a circuit, the electron leaves the circuit via a process called earthling, while they enter the circuit from a source. The circuit can carry two forms of current which are the alternating and direct current.

Hence the path along which electric current flows is called an electric circuit, thus the answer is A. electric circuit.

Note:
An electric circuit is a path through which electrons from a voltage or current source flows whereas insulators and conductors are material which either doesn’t allow or allows the flow of current through them. While the resistor is an electrical component, which resists the flow of charges.
