Look at these components. All these are dye oats. Yes any conductor, this. Now look at this one and this one. They have a silver lining. That silver one is a cat. This is also a diode of PN junction diode. This is also PN junction diode. This diode, this part is flat. This one is the anode. This part is a cat positive negate. Your this side is positive. This is negate cat. These are also diodes, the elitins. The longer ones are and longer ones are the cat.
