Diode junction voltage

Measure the voltage bias ofthe different diodes with a multimeter in the diode option follows and list them on the table.

Type of diode | Diode voltage |
1N4003 | 0.531v |
1N4148 | 0.564v |
LED RED | 1.74v |
LED GREEN| 1.82v |
LED ORANGE | 1.80v |
LED INFRARED | |

Now measure the voltage in reverse polirazación different diodes with a multimeter in the diode option follows and list them on the table.Type of diode | Diode voltage |
1N4003 | ∞v |
1N4148 | ∞v |
LED RED | ∞v |
LED GREEN | ∞v |
LED ORANGE | ∞v |
LED INFRARED | ∞v |

Diode characteristic curve

assembling the circuitfollowing the different varieties diodes and diode in the votaje 0.2 to 0.2 from 0 to 2 voltys and record in the table, then plot the diode current with respect to the voltage of the diode of each ofthe diodes.

Questionnaire
1.-)which is the principleof operation of the diode?
Voltage is applied across the OLED such that the anode is positive with respect to thecathode. This causes an electron current which flows in the opposite direction from...
