Answer:
The correct answer is the option c) A circuit is an unbroken loop of conductive material throught which electrons flow continuously
Step-by-step explanation:
An electrical circuit is a closed path that runs through an electrical current in order to carry this current from some elements that produce it to other elements that consume it.
The basic elements of an electrical circuit are:
Electric current generator (battery or battery): They are the source of energy that produce and maintain the electric current through the circuit.
Conductors (cables or wire): They carry the current to the other components of the circuit.
Receivers: they are the elements that transform the electrical energy that reaches them into another type of energy.
Command or control elements: allow directing or cutting at will the passage of electric current within the circuit.
Protective elements: they are used to prevent damage to facilities, devices and people.
The electric current is a movement of electrons, therefore, any circuit must allow the passage of electrons through the elements that compose it (that is why the cables or wires must be conductive materials). Electric current is produced by a difference in electrical charges. This difference in charges can be found in the electric current generator, which has two points with differences in charges (the positive pole and the negative pole). By connecting a conductor cable between the poles, an electric current will be established. The greater the difference in charge (or electrical voltage), the more electrons the conductor will travel through.
Then the correct answer is the option c) A circuit is an unbroken loop of conductive material throught which electrons flow continuously. If a circuit were an interrupted loop of conductive material, the electric current would not circulate and the circuit would be open.
