ELECTROMAGNETIC RELAY
AIM- To study Electromagnetic Relay
APPARATUS-Relay 16v,18v etc 2load (bulb) power supply .
THEORY-
Relay is electromagnetic device is made up of electromagnet& two contact arrangement & two contact arrangement relay has generally contact, two for coil one for common & other to different two loads . In relay ‘C’ point & one load point are short this is called as NC (Normally closed) & other load contact is ‘NO’ (Normally open).
When use energized the relay its working voltage relay operates and its No contact get closed to common point & NC contact get open its way transfer one load OFF and other load ON. Generally relay is used to contact one load & to disconnect other load at the time relay are available in 6v,9v,12v,29v D.C etc. Also A.C related are available relay sometimes have more than 2 contact note that the signal as100times smaller larger voltage can be measured by celebrating the scope alternate in X, position an then switching over to be X-100 position with the oscilloscope setting in the celebrating position practice measuring several unknown voltage of different frequency . With the knowledge gained by working with C.R.O complete table.
