Electrical Class and Sayonara En.Redzuan

Assalamualaikum and very good evening to readers out there...

This time, the class start with one hour of completing and finishing the circuit given to us... As last week, my circuit is already in good shape and its light up like it suppose to,how this time, my double sided circuit gone haywire.. i dont know what happen as the connection is same with the last time and nothing is wrong with it. It sad to not able to submit both of the circuit even though the other circuit is perfectly working. in one hour, i try to fix it but the problem still there... finish the one hour, En. Redzuan start the class of electrical.

The topic is how electricity is generated in Malaysia and what is Malaysia using(phase). First, Malaysian electric source is from Hydro generator, Gas, Coal and Oil. But now, Malaysia is most depend on the Hydro. En. Redzuan said, if there is a chance, he want to make a visit to a dam in Kelantan where the bus can enter near the turbine(mean we can see how it works!). Next, phase...Phase, there are 3 type of phase that is Red, Yellow and Blue. There are two mode, star and delta mode(dont know right or not) which at star mode, there are neutral.

Then, En Redzuan talk about the circuit breaker, the ELCB(Earth Leakage Circuit Breaker) and RCCB(Residual-Current Circuit Breaker).For home, we using the ELCB and for industry, they using RCCB, for more information on the ELCB and RCCB you can visit Earth_leakage_circuit_breaker and Residual-current_device .

After finish with the electrical briefing part, En Redzuan then start with the demonstration of the assembling the lamp for our practical. For your information, we have to divide into group and each one have 2 person. Then he start explaining on how to cut the wire the correct way, how to connect the wire to the lamp, and much more.

He also show how to connect the plug extension and check whether the things is connected or not..hest test it using his own made buzzer.. After that, the class finish...

The last class with En. Redzuan, we have an assessment on assembling the extension and the fluorescent lamp(dc and ac) connection.

Before we start the assessment, once again En Redzuan showed us how to assemble the part. After that, its the time that we do it on our own. Syahmi and I form the group and start doing the job. Im doing the lamp and Syahmi take over the extension. Its my first time assembling the lamp and its quite slow.. Never mind of that my lamp housing is not good because its already break at the connector but still usable.. After finish asembling the lamp, i try to turn on it but its not on..at the same time the other group also try to on the lamp but not successful...Then the room is short..however, i check my lamp connection and all is correct, then i try again and by adjusting the lamp a little bit at its connector, and then, its light up..After that, syahmi finish with the extension, after few test and inspection by En.Redzuan, we go on with DC... The DC connect directly and we finish it successfully..

After that, its time to back and time to say goodbye to En.Redzuan as its the last class with him for this semester.. That all..Thank you..
