When N-type (cathode) is connected to +ve terminal and P-type (Anode) is connected –ve terminal of the supply voltage is known as reverse bias and the potential barrier across the junction increases. The current increases with increasing forward voltage. At some forward voltage, the potential barrierĪltogether eliminated and current starts flowing through the diode diodeĪnd also in the circuit. The potential barrier is reduced when diode is in the forward biased condition. When P-type (Anode is connected to +ve terminal and n- type (cathode) is connected to –ve terminal of the supply voltage, is known as forward bias. When external voltage is zero, circuit is open and the potential barrier does not allow the current to flow. The V-I characteristics of the diode are curve between voltage across the diode and current through the diode. THEORY:A p-n junction diode conducts only in one direction.
