All comments which are given above is totally wrong because ohms law given by them is totally wrong. i is directly proportional to v.

R = V/I.

SO, R = 12/3.6 = 3.333333333333333.

ACCORDING TO OHM'S LAW,
R(resistance)=V(voltage)/I(current)
=12/3.6
=3.33 kilo-ohm

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.

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=12
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.

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

Absolutely its 3.33kilo ohms.
