Question: 1 / 400

What best describes a relay coil's function?

It measures electrical current.

It stores electrical energy.

When energized it activates contacts to either open or close.

A relay coil's function is to activate contacts to either open or close when it is energized. This means that when an electrical current flows through the coil, it creates a magnetic field that then pulls the contacts, causing them to either open or close. This action allows the relay to control the flow of electricity and switch circuits on or off. Option A is incorrect because a relay coil does not measure current, but rather uses it to create a magnetic field. Option B is incorrect because a relay coil does not store energy, it only uses it temporarily to create the magnetic field. Option D is incorrect because a relay coil does not convert electrical energy into mechanical energy, but rather uses electrical energy to generate a magnetic field. Therefore, the correct answer is C.
