Question : 11 of 29
Marks: +1, -0
Assuming that the two diodes D1D_1 and D2D_2 used in the electric circuit shown in the figure are ideal, find out the value of the current flowing through 1Ω1 \Omega resistor.
Solution:  
D1D_1 is forward biased. D2D_2 is reversed biased. Hence, the circuit may be considered as:
So, the current through 1Ω1 \Omega resistor is
  6V(2+1)Ω=2A\; \frac{6 \text{V}}{(2+1) \Omega} = 2 \text{A}
