Pn Junction Diode Forward Bias Circuit Diagram. When forward bias is applied the electron and holes at the junction recombine and energy released is emitted in the form of light. Keep in mind we are talking about a variable power source an ammeter in milli ampere range and a voltmeter.
Lets get a voltmeter and ammeter and connect it to the forward biased circuit of pn junction diode a simple circuit diagram is shown below which has a pn junction diode a battery in picture it is not shown as variable. A light emitting diode is simply a forward biased p n junction which emits spontaneous light radiation. Whereas during reverse bias the diode is in non conducting or acting as an open circuit.
Whereas during reverse bias the diode is in non conducting or acting as an open circuit.
Forward biased i v characteristics for p n junction diode with the effect of series resistance the above figure is v i characteristics that reveals the impact of the series resistance. In this physics digital electronics video lecture in hindi for class 12 we explained forward and reverse bias in p n junction diode in terms of depletion l. The biasing conditions of p n junction s diode clearly state that during forward bias the diode is in conducting mode acting like a closed circuit. Keep in mind we are talking about a variable power source an ammeter in milli ampere range and a voltmeter.
