Question

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 $0.7 V$ . For the input voltages shown in the figure, the voltage (in Volts) at point $A$ is .

Open in App

Solution

The diode on the right-hand side is reversed biased, while the one on left-hand side is forward biased.

Hence, voltage at $A$ ,

$V_{A} = 12.7 - 0.7 = 12 volts$
