Determine V_q and I_d for the circuits shown in the figure below

Solution

Let two diodes to be ideal and on state voltage drop across each diode is zero. so both 2k Ohmare parallal and series to 2k Ohm

So Vq=10*(2k)/(2k+1k)=6.667V

Id=10/(2*3k)=1.667A. (total current divides into half for two diodes)
