If it is a light emitting diode it is there to let you know that the relay is energized.
In my experience, when a DC current is removed from a coil, the polarity of the magnetic field reverses and if it weren't for the diode, the relay would "chatter".
The diode polarity is oppsite of the actuating voltage.

Is a relay and a diode the same?
No.
What is the purpose of the diode in the GM AC clutch circuit?
The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit. The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit.
What indicate 1 in 1N4007 diode?
general purpose diode with 1000V reverse breakdown.
How does a quenching diode work?
Quenching diodes are used to protect the control circuit of a relay. Power is applied to a relay's coil to close it. When this power is released there is a backwards flowing pulse that can wipe out solid state devices like transistors, LEDs, chips, etc... The quenching diode is applied in parallel with the relay coil so that the cathode is on the positive side. During normal operation, the diode doesn't conduct and the relay operates normally. When the relay is switched off, the "reversed" back pulse is absorbed due to the low voltage drop of the diode which limits the spike.
What is the purpose of a diode in a cordless drill or power screwdriver?
it controls the speed. when the diode is busted it gains into fullspeed
Is a relay and a diode the same?
No.
Why do you put a diode across a relay coil?
If the current through a coil is interrupted, the coil generates a high voltage (such as in the old car ignition coils). The diode provides a path for the current to decay naturally, thus avoiding the high voltage.
What is the purpose of clamping diode in a positive diode AND gate?
ttt

What is the purpose is of a diode?
The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.

What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
Is relay active or passive?
diode is a two terminal passive non linear device.
What is the purpose of half wave rectifier?
it has only one diode
What is the purpose of an automotive relay?
The Purpose of a Relay is to control multiple electrical components at once.
