1. Define Knee Voltage?
Ans. - Knee voltage is the forward voltage at which the flow of the current through the PN
junction of the diode increases rapidly.
2. What is Rectification?
Ans. - The process in which the alternating current is converted into direct current is called
Rectification. A diode can be used as a rectifier.
3. Writedown the fullform of MOSFET and types of MOSFET?
Ans. - MOSFET – Metal Oxide Semiconductor Field Effect Transistor. MOSFET is of two types.
i)
Depletion Type
ii)
Enhancement Type
Both are of two types N channel and P channel.
4. Define α and β?
Ans. – α is defined as the ratio between collector current and emitter current.
∆𝑰𝒄
I.e. α = ∆𝑰𝒆
β is defined as the ratio between collector current and base current.
∆𝑰𝒄
β = ∆𝑰𝒃
5. What is Zener diode and where it is used?
Ans. – Zener diode is the special type of diode which is made for operation in reverse bias condition.
It is used for voltage regulator and clipping circuit.
