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 0.7V. For the input voltages shown in the figure, the voltage (in Volts) at a point A is ______________ 
Option: 1 12
Option: 2 10
Option: 3 40
Option: 4 24
Answers (1)
We want to find VE
By applying kvl in AEFBA
12.7 - 0.7 - VE = 0.
implies
VE = 12V
Hence the correct option is (1).
