When a diode or any two-terminal component is connected in a circuit, it has two biased conditions with the given supply. They are Forward biasedcondition and Reverse biased condition. Let us know them in detail.
Forward Biased Condition
When a diode is connected in a circuit, with its anode to the positiveterminal and cathode to the negative terminal of the supply, then such a connection is said to be 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 forward biased condition.
Reverse Biased Condition
When a diode is connected in a circuit, with its anode to the negativeterminal and cathode to the positive terminal of the supply, then such a connection is said to be 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 condition.
Let us now try to know what happens if a diode is connected in forward biased and in reverse biased conditions.
