Marks: +1, -0

Assuming that the two diodes D1 and D2 used in the electric circuit shown in the figure are ideal, find out the value of the current flowing through 1Ω resistor.

Solution:

D1 is forward biased. D2 is reversed biased. Hence, the circuit may be considered as:

So, the current through 1Ω resistor is
‌

(2+1)Ω

=2A
