Fig. below shows two \[p-n\] junction diodes along with a resistance R and a d. c. battery E. Indicate the path and direction of flow of appreciable current in the circuit.           

Answer:

                    In the given circuit, \[{{D}_{1}}\] is reverse biased and does not conduct while \[{{D}_{2}}\] is forward biased and conducts current. So a current flows along the path \[E\to R\to {{D}_{2}}\to E\]
