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 point A is ________

Solution

Let $V_B=0$
Right diode is reversed baised and left diode is forward biased
$\therefore V_A=12.7-0.7$
$=12$ Volt
