R = V÷I.
R = 12÷3.6.
= 3.3Ohms.
R = 12÷3.6.
= 3.3Ohms.

V = IR ,
R = V/I,
R = 12/0.36A,
R = 33.3 ohm.
R = V/I,
R = 12/0.36A,
R = 33.3 ohm.

According to Ohms law;
R = V/I.
R = 12/3.6 = 3.33.
R = V/I.
R = 12/3.6 = 3.33.

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

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.

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

According to ohms law.
V = IxR.
R= V/I.
So data given.
V = 12V.
I = 3.6 mA.
R = V/I.
= 12/(3.6*10^-3).
= 12*10^3/3.6. (Here denominator 10^-3 shifted to numerator i.e 10^3).
= 12000/3.6.
= 3.3 kilo ohms.
V = IxR.
R= V/I.
So data given.
V = 12V.
I = 3.6 mA.
R = V/I.
= 12/(3.6*10^-3).
= 12*10^3/3.6. (Here denominator 10^-3 shifted to numerator i.e 10^3).
= 12000/3.6.
= 3.3 kilo ohms.
