Resistor

	Resistors limit current on a circuit. How can we read a resistor? It is very easy. On the resistor, there are several colors. Color used are black, brown, red, orange, yellow, green, blue, violet, gray, and white.

This resistor has colors of red, orange, green, and gold.

Resistance can be calculated by

R = (First digit * 10 + second digit) * multiplier.

Therefore,

R = (Red * 10 + Orange) * Green = (2 * 10 + 3) * 100,000 = 230,000 ohm.


	Here is the color table for calculating resistance:
