Haylee Roberson · Answer 1

d) Neither A or B is correct

Explanation:

A relay is defined as a switch of a circuit. It is use to permit little quantity of current to manage high current circuit. Therefore, option d is correct.

Norah · Answer 2

d) Neither A nor B is correct

Explanation:

We are given the arguments of two technicians thus:

Technician A says that the relay's coil is energized when the circuit's control switch is open. This action connects power to the load circuit.

Technician B says that a relay is an electric switch that allows a large amount of current to control a low-current circuit.

A relay is an electrical actuator/switch that allows a relatively small electrical voltage or current to control a larger voltage or current. This negates Technician B statement about the functionality of the actuator/switch.

When the control circuit switch is open no current flows to the coil of the relay negating Technician A statement.

Consequently neither Technician A nor B's argument is correct option D is right.
