Solution


Q.

The given circuit has two ideal diodes connected as shown in the figure. The current flowing through the resistance R1 will be           [2016]
1 2.5 A  
2 10.0 A  
3 1.43 A  
4 3.13 A  

Ans.

(1)

Diode D1 is reverse biased so, it will block the current and diode D2 is forward biased, so it will pass the current.

Hence, equivalent circuit becomes as shown in the figure.

Current in the circuit = Current flowing through the resistance R1

    =102+2=2.5 A
