The load is placed in full load condition and the zener voltage (Vz), Zener current Connection are made as per the circuit diagram 4. VFL=Voltage across the diode, when load is connected. The percentage regulation is given by the formula ((VNL-VFL)/VFL)X100 VNL=Voltage across the diode, when no load is connected.

The voltage regulation of any device is usually expressed as percentage regulation 2. A graph is plotted between zener current (IZ) and zener voltage (VZ). The zener current (IZ), and the zener voltage VZ.) are observed and then noted in the tabular form. The Regulated power supply voltage is increased in steps. Connections are made as per the circuit diagram. Once the diode starts conducting it maintains almost constant voltage across the terminals what ever may be the current through it, i.e., it has very low dynamic resistance.

High current through the diode can permanently damage the device To avoid high current, we connect a resistor in series with zener diode. This voltage is called Break down Voltage. But if the reverse bias is increased, at a particular voltage it starts conducting heavily. A p-n junction diode normally does not conduct when reverse biased. Theory:A zener diode is heavily doped p-n junction diode, specially made to operate in the break down region.

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 вЂ“ve is connected to the anode of the diode. Connections are made as per the circuit diagram 2. The reading of voltage and current are tabulated. Note down the corresponding current flowing through the diode and voltage across the diode for each and every step of the input voltage. Switch on the power supply and increases the input voltage (supply voltage) in Steps. Is connected to the cathode of the diode,ДЈ. For forward bias, the RPS +ve is connected to the anode of the diode and RPS вЂ“ve 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 вЂ“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 barrierДЄltogether eliminated and current starts flowing through the diode diodeДЄnd 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 вЂ“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.
