Final Year Project briefing and further research relay.

To gain knowledge from the briefing.
To search the related information of the relay.

Contents / Procedures:
For this week, there is Final Year Project briefing at TTL 1. The committee is Dr  Mohd Khairil bin Rahmat and Mr Shamsul Zahari bin Shahidin. Some point of the briefing is on the T-Shirt, claiming budget and submission of the report for FYP Sem 2 and Degree students. Plus, to reminds the students on the presentation day for Degree Sem 1 and Engineers Day for Degree Sem 2 and Degree students.
Internet research has been done in order to know more on the relay.


Relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used.
Relays are used where it is necessary to control a circuit by a low power signal or where several circuits must be controlled by one signal.
Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on and off so relays have two switch positions.
The coil of a relay can passes a relatively large current, typically 30mA for a 12V relay, but it can be as much as 100mA for relays designed to operate from lower voltages.
Relays are usually SPDT or DPDT
