Trivia 3 ~ Answer 3 – Anode and Cathode

A semiconductor diode is a two-terminal electronic component with a positive-negative junction. This is also called a Rectifier. The anode which is the positive terminal of a diode is represented with A and the cathode, which is the negative terminal is represented with K. To know the anode and cathode of a practical diode, a fine line is drawn on the diode which means cathode, while the other end represents anode.

Forward Biased Condition
When a diode is connected in a circuit, with its anode to the positive terminal and cathode to the negative terminal of the supply, then such a connection is said to be the forward-biased condition. This kind of connection makes the circuit more and more forward biased and helps in more conduction. A diode conducts well in forwarding biased conditions.

Reverse Biased Condition
When a diode is connected in a circuit, with its anode to the negative terminal and cathode to the positive terminal of the supply, then such a connection is said to be the Reverse biased condition. This kind of connection makes the circuit more and more reverse biased and helps in minimizing and preventing the conduction. A diode cannot conduct in reverse biased conditions.
