PHYSICS INVESTIGATORY PROJECT ON
RELAY AS AN OSCILLATOR
A relay is an electromagne0c switch. Do you know that we can use it to build oscilla0ons? Consider there are two LEDs. First, one of the LEDs glow and then it gets OFF. Then the second LED glows and it goes off. Then the first one again glows and the cycle repeats itself.
In this circuit, we can control the number of 0mes the relay gets ac0vated and deac0vated in one second. This circuit uses
a capacitor, two LEDs, a relay and a momentarily push switch. When the switch is pressed, the current oscillates between LEDs, due to which they glow alternately. A clock sound is heard periodically. We can also modify the circuit to speed up the oscilla0ons.
So, get ready to create some real fast oscilla0ons!
