Dopant is an element or compound which is used to improve the properties of a semiconductor.

First you need to know the LED voltage drop. It is safe enough to assume 1.7 volts for non-high-brightness red, 1.9 volts for high-brightness, high-efficiency and low-current red, and 2 volts for orange and yellow, and 2.1 volts for green.

We are using the resistance to restrict the excessive flow of current through the device. And that resistance is known as "current limiting resistor".

Because of excessive there are chances of breakdown (zener or avalanche). So current limiting resisters are used.

Because diodes are low power semiconductor devices thats range between 1.5v to 12v , so we have to limit the heavy currents.
