I want to watch Camp Rock 2...

Disney US had shown Camp Rock 2 yesterday. And yet, I am still left hanging here, getting more and more impatient.

Seriously? I am already so impatient about it, countdown clock only appear to trigger my emotions...

Found this poster somewhere. Found it nice :P Junior rockers! Woohoo!

Starting today, I will be adding a section of 'Case Study of the Day', which will include things I learned in school. You might find this lame, but this can help me to revise and connect books with real life. I love experiments :)

Case Study of the Day: Three Pin Plug

Subject: Physics

Topic: Practical Electricity

Live Wire: This is where the current flows in, 240V

Neutral Wire: This is where the current flows out, 0V, voltage is given to the appliance already

Earth Wire: This is where current flows when there is a fault, 0V (unless you want the circuit to be faulty. In any other times, it shouldn't have any current passes through it). Should there be any fault during the process, a large current will flow in the live wire, and returns to the earth via the Earth Wire. It is used as a safety measure. Another condition is when the live wire exposed due to wear and tear, touches the metal casing of the appliance. The Earth Wire is connected to the metal casing so that when the metal casing become 'live', current will then be directed back to Earth with the metal casing. Earth Wire protects the user from electrocuted.

Fuse: It is inserted in the Live Wire, so that it will melt and break the circuit when the large current flows during the fault exceeds the rating. Hence, the appliance is disconnected from the high voltage of the live wire. This prevents excessive current flowing into the appliance.

Similarity and difference of Earth Wire and Fuse:

1) Similarity:

Both are safety measures

2) Difference:

Earth Wire protects the user while Fuse protects the appliance and the user as well.

How to wire a three pin plug?

1) By means of a wire stripper or a cutter, remove a sufficient amount of insulation from each of the three wires. Care must be taken to ensure that the wire strands do not break off.

2) The wire strands are then twisted together gently.

3) Secure the three wire strands to the correct terminal according to the color code by means of wrap round screws. Check that the insulation on the wires extends right to the pins.

4) Finally, tighten the cord grip to grip the cord firmly.

I need some motivation to study now... Complacency, procrastination and laziness, please get out of me immediately!
