A p-n junction diode has a forward bias ...

A p-n junction diode has a forward bias resistance of 10`Omega` and a reverse bias resistance of 10 k`Omega`. It is connected in series with a resistance of 990 `Omega` and a.d.c. source of 5V in such a way that the negative terminal of the source is connected to then region of the p-n junction. What is the current flowing in the circuit?

A

10 mA

B

5 mA

C

2.5 mA

D

12.5 mA

Text Solution

Verified by Experts

The correct Answer is:
B
Diode is forward biased.
`therefore` Current (I)=`V/(R+R_f) = 5/(990+10) `= 5 mA
