Diode D1 is forward biased and D2 is reverse biased ∴ VA=12.7-0.7=12V.

Q. Both the diodes used in the circuit shown are assumed to be idea land have negligible resistance when these are forward biased. Built in potential in each diode is $0.7 V$ . For the input voltages shown in the figure, the voltage (in Volts) at point $A$ is________.
Given 8.4

Diode $D_{1}$ is forward biased and $D_{2}$ is reverse biased
$∴ V_{A} = 12.7 - 0.7 = 12 V .$
