|ACCORDING TO OHM'S LAW,
|Vinay said: (Feb 23, 2011)|
|Ohm's Law :- V = I*R
But here we adjust the terms as,
R = V/I
= 12/3.6 * 10^-3 ...(^ sign is POWER )
= (12/3.6)* 10^3 ...(shifting of 10^-3)
= 3.3 * 10^3
R = 3.3 kilo-ohm

|I want range of mA and killo-ohm. Any one say?|
|Surekha said: (Jul 10, 2011)|
kilo ohm =10^3

|Nice answer vinay|

|Absolutely its 3.33kilo ohms.|

|V=12, I = 3.6mA=0.0036A.
3.3 kilo ohm.

|According to ohms law,
FINALLY R=3300 OHMS.
|Pramod Shinva said: (Aug 4, 2013)|
|Over formula is suitable for only in Ohms Volts Amps. So we should be convert mA to Amps.(3.6MA = 3600A).
R = V/I.
= 0.0033ohms (0.0033ohms = 3.33 kohms).
= 3.3 kohms.

|Assuming Temperature is constant, By OHM'S law,
V = RI.
hence; R= V/I.
R = 12/36000.
R = 3333.3333 ohms.
|Shahadat said: (Oct 3, 2013)|
|@Jayadhar you are right,
Because of Temperature is constant And
According to OHM's law,
V = RI.
R = 3.3 k ohm's.
|Avatar said: (Oct 8, 2014)|
|R = V/I.
SO, R = 12/3.6 = 3.333333333333333.
|Ravi said: (Aug 22, 2015)|
|According to ohms law.
V = IxR.
So data given.
V = 12V.
I = 3.6 mA.
R = V/I.
= 12*10^3/3.6. (Here denominator 10^-3 shifted to numerator i.e 10^3).
= 3.3 kilo ohms.

|All comments which are given above is totally wrong because ohms law given by them is totally wrong. i is directly proportional to v.|
|Imrosekhan said: (Nov 16, 2016)|
|As we know that v = ir.
According to ohm's law.
So, R = V/I.
Substitute those values in the above equation.
we get, 12/10powerten(-3) = 3.3kiloohms.

|Can anyone let me know the conversation of (-3) to (+3)?|

|Thank you all for explaining.|
