We will use the formula of Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points.


V=RI

where

V is the voltage

R is the resistance

I is the current

In our case we have

V=12 V

I= 2 A

we need to find the resistance, so we need to isolate the R in the formula


R=(V)/(I)

Then we substitute the values


R=(12)/(2)=6\Omega

therefore

the resistance of a circuit in which a 12-volt battery produces a current of 2 amps be 6 ohms.​
