0.7 v is the cutoff voltage of silicon.

First active diode need for 0.7 voltage.
Since the voltage across R1 = 12-0.7 = 11.3.
Since the voltage across R1 = 12-0.7 = 11.3.

Vout=Vin-Vsi,
Vout=12-0.7
=11.3
Vout=12-0.7
=11.3

0.7 is the Voltage across the pn diode so according to the kvl answer is 11.3

0.7v is the cut off voltage of Silicon.

0.7v is Barrier Voltage which must be applied for diffusion to happen.

But resistance in kilo ohms and voltage in volts so both are different in systems. Answer should be 11.3 * 10 to the power -3.

Since diode is silicon so forward drop at diode is 0.7V remind voltage of Vin = 12-0.7 = 11.3

As the forward bias Si P-N Junction produces a barrier voltage of 0.7 V. Barrier voltage will oppose forward biasing voltage 12V .
That's why 12-0.7 = 11.3V is the answer.
That's why 12-0.7 = 11.3V is the answer.
