A switch is always connected to the: (A) Live wire (B) Neutral wire (C) Earth wire (D) None of these

Hint We know that the switch is defined as a component which has the function of controlling the open-ness or the closed-ness of an electric circuit. They allow the control over current flow in a circuit. Based on this concept we have to answer this question. Complete step-by step answer A switch is always connected to live wire. We know that the purpose of the switch is to break or connect an electric circuit, but they must be correctly connected in circuit. Hence, the correct answer is Option (A). Note It should be known to us that an electrical wire through which there is a flow of the electrical current, is known as the live wire. The neutral wire is the wire that returns the electricity to the generators of the power station after it has passed through an electrical device to complete the circuit. The earth wire is used in order to protect us from an electric shock. The earth wire gives us a path for a fault current to flow to the earth.
