Two ideal diodes are connected to a battery as shown in the circuit. The current supplied by the battery is                                                                                                                                              [AIPMT (S) 2012]

A)  0.75 A      

B)  zero                 

C)  0.25 A 

D)  0.5 A

Correct Answer: D

Solution :

Here m circuit \[{{D}_{1}}\] is forward bias and \[{{D}_{2}}\] is reverse bias. Current will flow only in diode \[{{D}_{1}}\]

The current supplied by the battery

\[i=\frac{5}{10}=0.5A\]
