Pn Junction Diode Circuit Diagram. A diode is called as p n junction diode if it is formed by p type on one side and n type on the supplementary one or reverse direction the diode has to be in forward biased condition to permit the electric current flow. 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.
In the forward biased mode the zener diode operates as a p n diode. When forward bias is applied the electron and holes at the junction recombine and energy released is emitted in the form of light. A light emitting diode is simply a forward biased p n junction which emits spontaneous light radiation.
In the forward biased mode the zener diode operates as a p n diode.
B light emitting diode led. A light emitting diode is simply a forward biased p n junction which emits spontaneous light radiation. In the forward biased mode the zener diode operates as a p n diode. A diode is called as p n junction diode if it is formed by p type on one side and n type on the supplementary one or reverse direction the diode has to be in forward biased condition to permit the electric current flow.
