All about diodes

What is diode: A  diode  is an electronics component made from a combination of a (1) P-type and (2) N-type (3) semiconductor material, known as a p-n junction, with leads attached to the two ends. The lead attached to the n-type semiconductor is called the  cathode . Thus, the cathode is the negative side of the diode. The positive side of the diode — that is, the lead attached to the p-type semiconductor — is called the (6) anode .   When a voltage source is connected to a diode such that the positive side of the voltage source is on the anode and the negative side is on the cathode, the diode becomes a (7) conductor and allows current to flow. 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 (8) insulator. Voltage connected to the diode in this direction is...
