In the given circuit, the potential difference between A and B is

A

0

B

5 volt

C

10 volt.

D

15 volt.

Text Solution

Verified by Experts

The correct Answer is:
C
Here p-n junction is forward biased. If p-n junction is ideal, its resistance is zero. The effective resistance across A and B
`=(10xx10)/(10+10)=5KOmega`
Current in the circuit
`I=(30)/((10+5)xx10^(3))=(2)/(10^(3))`
`therefore" Current in each arm"=(I)/(2)=(1)/(10^(3))A.`
Pot. diff. across A and B
`=(1)/(10^(3))xx10xx10^(3)=10V`
