The current flowing in the circuit can be found by applying Ohm's law:
[tex]V=IR[/tex]
where
V is the voltage of the battery
I is the current flowing in the circuit
R is the resistance of the circuit

In our problem, V=12 V and [tex]R=2 \Omega[/tex], so if we re-arrange the previous equation and we use these data, we find the current in the circuit:
[tex]I= \frac{V}{R}= \frac{12 V}{2 \Omega}=6 A [/tex]

Therefore the correct answer is C).
If one resistor is connected to a battery and has a resistance of 2 ohms and the battery has a voltage of 12 volts, the current passing through the circuit is 6 amps. If V=IxR, then I (current) = V (voltage)/ R (resistance) = 12 V/2 Ohms = 6 amps.
