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.
On the left, diode D1 is forward biased and allowing current to flow through the circuit. In essence it looks like a short circuit. On the right, diode D2 is reverse biased. Current cannot flow through the circuit, and it essentially looks like an open circuit.
