@Jayadhar you are right,
Because of Temperature is constant And
According to OHM's law,
V = RI.
R = 3.3 k ohm's.

Assuming Temperature is constant, By OHM'S law,
V = RI.
hence; R= V/I.
R = 12/36000.
R = 3333.3333 ohms.
V = RI.
hence; R= V/I.
R = 12/36000.
R = 3333.3333 ohms.

Over formula is suitable for only in Ohms Volts Amps. So we should be convert mA to Amps.(3.6MA = 3600A).
R = V/I.
= 12/3600.
= 0.0033ohms (0.0033ohms = 3.33 kohms).
= 3.3 kohms.
R = V/I.
= 12/3600.
= 0.0033ohms (0.0033ohms = 3.33 kohms).
= 3.3 kohms.

According to ohms law,
V=IR
V=12v
I=3.6ma
R=V/I
I=0.0036AMPS.
R=12/0.036
FINALLY R=3300 OHMS.
R=3.3KOHMS.
V=IR
V=12v
I=3.6ma
R=V/I
I=0.0036AMPS.
R=12/0.036
FINALLY R=3300 OHMS.
R=3.3KOHMS.

V=12
I=3.6mA
R=12/3.6*10^-3=12/0.036=3.3kohms.
I=3.6mA
R=12/3.6*10^-3=12/0.036=3.3kohms.

V=12, I = 3.6mA=0.0036A.
V=IR.
R=V/I=12/0.0036=12*10^4/36=10^4/3=10000/3=3333.33 ohm.
3.3 kilo ohm.
V=IR.
R=V/I=12/0.0036=12*10^4/36=10^4/3=10000/3=3333.33 ohm.
3.3 kilo ohm.

I=V/R
V=12V
I=3.6mA=3.6*10^-3
R=V/I
R=(12/36*10^-4)Ohm
=(1/3)*10^4ohm
=0.333*10^4ohm
=3.33*10^3ohm
=3.33kilo-ohm
V=12V
I=3.6mA=3.6*10^-3
R=V/I
R=(12/36*10^-4)Ohm
=(1/3)*10^4ohm
=0.333*10^4ohm
=3.33*10^3ohm
=3.33kilo-ohm
