Answer 1

Here is your answer friend

Answer 2

Hello mate,

# Options should be -

1. tunnel diode
2. shotckey diode
3. laser diode
4. hot carrier diode

◆ Answer -

(1) tunnel diode

◆ Explanation -

• Phenomenon in which current in the circuit decreases with increase in voltage is called negative resistance.
• Tunnel diode has p-type & n-type semiconductor acting as anode & cathode respectively.
• If the voltage is increased above peak voltage in tunnel diode, current starts decreasing.
• Gunn diode & IMPATT diode also show negative resistance.

Hope this helped you.
