Solution

The correct option is C $2.0 V$
We know that voltage drop across a silicon diode is $0.7 V$ .
Since diode and resistor are connected in series so the voltage across the resistor $= 2.7 - 0.7 = 2 V$

A silicon diode which has a knee voltage of 0.7 V & negligible forward resistance has a pd across it as shown. Then the current through the diode is

V_{A} i s (A s s u m e, V_{γ} = 0.7 V)

V_{A}

V_{r} = 0.7 V
