In the following circuit, the current flowing through \[1k\Omega \]resistor is:          

A) 0mA                            

B) 5mA   

C) 10mA                           

D) 15mA

Correct Answer: B

Solution :

[b] \[1K\Omega \] Parallel to diode hence 5v across \[1K\Omega \]remaining 5V drop across 5000. \[V=IR\] \[5=1\times 500\] \[I={{10}^{-2}}A\] Apply ohm law across \[1K\Omega \] \[5=1\times 500\] \[I=5mA\]
