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.
The SCR start conduction when it is forward biased. For this purpose the cathode is kept at negative and anode at positive voltage. When the forward bias voltage is applied to the SCR, the junction J1 and J3 become forward biased while the junction J2 become reverse biased.
