Both the diodes used in the circuit shown are assumed to be
ideal and have negligible resistance when these are forward biased.
Built in potential in each diode is[IMAGE]. For the
input voltages shown in the figure, the voltage (in volts) at point A is
6x. Find x.

Show answer and solution

Let [IMAGE] Right diode is reversed biased and left diode is forward biased
