Question

When testing a normally opening relay contact with a de energized coil it should measure?

1) Open
2) Closed
3) Shorted
4) Cannot be determined

Answer 1

A normally opening relay contact should measure open when tested with a de-energized coil, as this is its default state.

Step-by-step explanation:

When testing a normally opening relay contact with a de-energized coil, it should measure open. A normally opening relay, also known as a normally open (NO) contact, is designed to be open when there is no current flowing through the relay coil. When the coil is de-energized, the relay's contacts are in their default state, which for a NO relay is open. This means that there should be no continuity between the contacts, and a multimeter would show an open circuit (or infinite resistance).
