Palomino Horse. The Palomino horse is not actually a particular horse breed but a color breed. Only those horses which meet certain specific standards of color coding can be called Palomino horses. The Palomino horse is a characteristic creamy golden tan. Its tail and mane are almost white.
Diode is an unipolar device, i.e. it has a p-type side and a n-type side, and their connection matters. Forward Bias: When the p-type side of the diode is connected to a higher potential than the n-type side, the diode is said to be forward biased, because it enhances the capability of the diode to conduct forward current.
Voltage connected to the diode in this direction is called forward bias. But if you reverse the voltage direction, applying the positive side to the cathode and the negative side to the anode, current doesn't flow. In effect, the diode becomes an insulator.
