In ideal condition drop is equal to 0 so answer is 1 mA.

Generally si or ge diode has consider 0.7v barrier. But in case of ideal it should be consider 0v, that's why answer is 1mA.

In case of ideal diode in forward bias voltage drop is 0.
Hence I= V/R.
I=12/12k.
=1mA.
Hence I= V/R.
I=12/12k.
=1mA.

It is right in case of ideal vd=0 because internal diod resistance is 0.
So I=12-0/12=1mA.
So I=12-0/12=1mA.

I=V/R.
V=12v.
R=12kohm.
I=12/12000.
I=0.001 amp.
I =1mA.
V=12v.
R=12kohm.
I=12/12000.
I=0.001 amp.
I =1mA.

I=?
I=v/r v=12 volt, r=12 k ohms or 1200 ohms
I=12/1200
I=0.01amps or 10 milliamps
I=v/r v=12 volt, r=12 k ohms or 1200 ohms
I=12/1200
I=0.01amps or 10 milliamps

Actually the diode is in ideal condition so there is no cut in voltage (0v). Answer should be 1mA.

Answer is A, b/c voltage drop across an ideal diode is 0v.

Ans Should be 1mA.
Beacause An ideal diode offers zero resistance in foreword bias & infinite resistance in reverse bias.
So Drop across ideal diode is Zero.

Answer is 1mA as they have mentioned it as a ideal diode.
