A square wave ( to ) is applied to a - junction diode, as shown. Draw the output wave-form across the diode which is assumed to be ideal.


Important Questions on Junction Diodes
A diode is connected to (rms) AC mains in series with a capacitor, as shown. What is the final voltage across the capacitor?

What is a junction diode? What is meant by forward-bias and reverse-bias in the case of p-n junction diode? Distinguish between the two biases.

With reference to a semiconductor diode, what is meant by forward bias?


With reference to a semiconductor diode, what is meant by depletion region?

Explain the formation of depletion region and potential barrier in a - junction diode. State how the thickness of depletion region changes when the - junction diode is forward biased.

Explain the formation of depletion region and potential barrier in a - junction diode. State how the thickness of depletion region changes when the - junction diode is reverse biased.

Draw a circuit diagram for - junction diode in forward bias. Sketch and discuss the voltage versus current graph for the same.
