Dynamic Resistance Of The Junction Node

Dynamics

What is a p-n junction diode? Define the term 'dynamic resistance' for the junction diode. With the help of a circuit diagram explain the working of a p-n junction diode as a full wave rectifier.

In a P-N junction , for a 0.2 V change in the forward bias voltage, the corresponding change in current is 20 mA. The dynamic resistance of the P-N junction is

The forward characteristic of p-n junction is shown in Fig.What is the dynamical resistance of p-n junction at 0.9 V ?

The i - V characteristic of a P - N junction diode is shown below. The approximate dynamic resistance of the P - N junction when a forward bias of 2 volt is applied

Which type of biasing result in very high resistance of p-n junction diode? Draw a diagram showing this bias.

A transistor having alpha = 0.99 is used in a common base amplifier. If the load resistance is 4.5 kOmega and the dynamic resistance of the emitter junction is 50Omega the voltage gain of the amplifier will be
