Question

The wire having a red plastic covering is a

Answer 1

As we know that there are four types of wire covering used. They are black, red, blue and white. We know that black, red, and blue coverings are used for hot wires and white is used in the case of neutral wire which is $\dfrac{{120}}{{208}}V$ circuit. We use brown, orange and yellow in hot wires and grey is used in the neutral wire which is of $\dfrac{{277}}{{480}}V$ . We should keep in mind that the wire having a black plastic covering is called a neutral wire.

Complete step by step answer:
We should know that the neutral wire is often confused with ground wire but in reality they have two distinct purposes. They carry currents back to the power source to better control and regulate voltage.
The wire that has a red plastic covering is known as a live wire. The red wire plastic covering signifies the phase in an electric circuit.
We should know that it is the live wire that cannot be connected to another red wire or bulb.
We use red wire in some types of switch legs.
Hence the wire having a red plastic covering is a live wire.

Note:
We should note their definition of a circuit i.e. a circuit is a path through which an electric current travels on and a simple circuit contains their components necessary to have a better functioning electric circuit They are named as a source of voltage, a conductive path, and a resistor. They i.e. Circuits are driven by flows. We should know that electrical wires are covered with plastic covering for safety purposes and this guarantees the electrons flowing through the wires will be safely done.
