The circuit shown in the diagram contains two diodes, each with a forward resistance of 30 \[\Omega \]and infinite reverse resistance. If the battery is of 3 V, then the voltage drop across 50 \[\Omega \]resistance will be

A)  2V                         

B)  5 V     

C)  1 V                        

D)  1.5V

Correct Answer: C

Solution :

                Diode Di get reverse biased where as diode \[{{D}_{2}}\] get forward biased. Voltage drop across 50 \[\Omega \]. resistance \[=\left( \frac{3}{150} \right)\times 50\] = 1 V
