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 0.7V0.7V. For the input voltages shown in the figure, the voltage (in Volts) at point A is ________
Both the diodes used in the circuit shown are assumed to be ideal and have negligible resistance when these are forward

Correct answer

0

Step-by-step solution

Both the diodes used in the circuit shown are assumed to be ideal and have negligible resistance when these are forward
Let VB=0{V}_{B} = 0
Right diode is reversed baised and left diode is forward biased
∴VA=12.7−0.7∴ {V}_{A} = 12.7 - 0.7
=12= 12 Volt
