OBSEVATION:S.NO APPLIEDVOLTAGE VOLTAGE ACROSSDIODE(V) Graph is plotted between voltage and current. The readings of voltage and current are tabulated 6. Note down the corresponding current flowing through the diode voltage across the diode for each and every step of the input voltage. Switch on the power supply and increase the input voltage (supply voltage) in Steps 4. For reverse bias, the RPS +ve is connected to the cathode of t he diode and RPS –ve is connected to the anode of the diode. Connections are made as per the circuit diagram 2.

For forward bias, the RPS +ve is connected to the anode of the diode and RPS –ve Connections are made as per the circuit diagram. The reverse bias current due to minority charge carriers. Therefore, the junction resistance becomes very high and a very small current (reverse saturation current) flows in the circuit. 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.
