The change in current through a junction diode is 12mA when the forward bias voltage is changed by 0.6 V. The dynamic resistance is

A

`500 Omega`

B

`300 Omega`

C

`150 Omega`

D

`250 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
Change in current , `Delta I=1.2 mA=1.2xx10^(-3)A`
Change in forward -bais volatage , `Delta V=0.6 v`
Dynamic Resistance,
`R_(dyn)=(Delta V)/(Delta I)=(0.6)/(1.2xx10^(-3))`
`=0.5xx10^3 =500 Omega` .

Which of the following statements is correct when junction diode is in forward bias?

In a p-n junction diode, the current I can be expressed as I= I_(0) "exp" ((eV)/(k_(B)T)-1) where I_(0) is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, k_(B) is the Boltzmann constant (8.6 xx 10^(–5) eV//K) and T is the absolute temperature. If for a given diode I_(0) = 5 xx 10^(-12) A and T = 300 K, then (a) What will be the forward current at a forward voltage of 0.6 V? (b) What will be the increase in the current if the voltage across the diode is increased to 0.7 V? (c) What is the dynamic resistance? (d) What will be the current if reverse bias voltage changes from 1 V to 2 V?
