This electromagnetic device was invented by Carl Friedrich Gauss and Wilhelm Eduard Weber in 1833 and there are two major types ac and dc.
For experimenting I use some different relays including finder relay,
at the end i use a 12 volt relay with a 9V battery to energize its coil after that i control 2 loads of 200 watts incandescent lamps.

Overall after watching this video you will learn all about electronics and electrical all kinds of 5v, 12v dc and ac 220v relays and also knows about how many types of relay in hindi language.
