 		 #106000 - Analysis
Responding to: ???'s previous message
I would like to know the following.
How a capacitor could be used to limit current.

Capacitors act like a resistor to AC voltages.Their impedance (resistance) relates to their capacity , the more capacity the less impedance.
How the LED lights up with such type of series parallel connection. i.e., can any one tell me how the current flows in such a circuit that makes all the LED's light up.

I can't recall the exact formula which related to this.But this type of supplies are called offline power supplies. you could try and search in google, you should find the formula with alot of other useful info's.
Lastly, how could a 100R 1W Metal Oxide Resistor act as a fuse.

Never heard of 'Metal Oxide Resistors' , but a resistor in series here provides a current limit and some sort of fusing .
