Electric lesson

On 19th December 2011, this is the last lesson with Mr.Redzuan, yet we also have a unforgettable experience.
That day, we learnt that how to connect wire in the extension wire and fluorescent lamp.


This make me recall back the chapter electric in form 3 which taught about the three types of wire which are live, earth, and neutral. In 3-pin plug, the normal current that flow through is 13A. If exceed that, the fuse which located beside the live wire will automatically cut off the supply of electricity to protect the plug and electric device.
First, Mr.Redzuan demonstrate to us that how to connect the wire correctly.


After that, it was our show time. We do the wiring in a group of two. Chin and I connected the wire carefully without any careless mistake to affect the extension wire and fluorescent lamp to function. We followed the instruction to connect the live, earth and neutral wire in the extension wire and fluorescent lamp.


Within one hour, we managed to complete the wiring and surprisingly, it actually function while testing! We were so happy. Next, we proceeded to the last part which connect the wire in DC in the fluorescent lamp. We were all provided a DC “cok” and had to do some wiring on it. Chin and I did it in one shot also. Fortunately, it also functioned.


We all have fun to do the wiring as never try it before. Hopefully I can fix the extension wire and fluorescent lamp from now on.
