To find the current flowing through the 2-Ω resistor, we can use Ohm's Law, which states that V = IR, where V is the voltage across the resistor, I is the current flowing through the resistor, and R is the resistance of the resistor. We know that the voltage across the 2-Ω resistor is the same as the voltage across the 4-Ω resistor, which is 12V. 
Thus, for the 2-Ω resistor, I = V/R = 12V/2Ω = 6 A. However, since this current is flowing against the direction of the arrow, we must take the negative of this value to get the actual current flowing through the resistor: -6 A. 
Therefore, the current flowing through the 2-Ω resistor is 4 A, which is the current flowing clockwise through the circuit.
