Question

In a(n) ________ latching relay with a single coil, the coil is pulsed with voltage at one polarity, and the solenoid plunger pulls in and is held in place by residual magnetism in the coil's core. When the coil is pulsed with voltage at the opposite polarity, the residual magnetism is canceled and the armature is released.

Answer 1

In a latching relay with a single coil, the solenoid plunger is pulled in and held in place by residual magnetism in the coil's core when the coil is pulsed with voltage at one polarity. When the coil is pulsed with voltage at the opposite polarity, the armature is released.

Step-by-step explanation:

In a latching relay with a single coil, the coil is pulsed with voltage at one polarity, causing the solenoid plunger to pull in and be held in place by residual magnetism in the coil's core. When the coil is pulsed with voltage at the opposite polarity, the residual magnetism is canceled, and the armature is released.
