For the circuit shown here, find the current flowing through the 1 ohm resistor. Assume that the two diodes D1 and D2 are ideal diodes

Diode D, is forward biased, while diode D2 is reverse biased.
Hence the resistances of (ideal) diodes D, and D2 can be taken as zero and infinity respectively.
The given circuit can therefore be redrawn as shown in the figure.
