Electronic Color Code: The resistors in the current circuit have 5 or 4 bands of color. The color bands represent the resistors resistance value, tolerance, and wattage rating.
One of the resistors have a thicker brown band farther away from the four other bands. The other 4 other bands are spread out; one band is red, two are black, and the fourth is brown. This resistor also has a blue base color.
The other resistors in the circuit have a thicker brown band followed by a brown band, two black bands, and another brown band. This resistor has a blue base.
Another resistor in the circuit has five bands brown, red, brown (or black, unclear because they are burnt), gold, and the thicker band is brown. If the colors are brown, red, black then this resistor has twelve ohm resistance. Because these resistors are connected in parallel the resistance per each resistor is 12/5 ohm. This resistor has a blue base.
Another resistor has a brown base and four bands of colors gold, black, purple, and yellow.
What do each of the colors mean and how to read them?
zener diode: allows current to flow from its anode to its cathode and in the opposite direction when the zener voltage is reached.
current limiting diode: limits the current to a maximal specified value for the device.
