Two conductors with a resistance of 2 ohms and 4 ohms are connected in parallel, and the current in the unbranched

Two conductors with a resistance of 2 ohms and 4 ohms are connected in parallel, and the current in the unbranched part of the circuit is 18 A. What current flows through the second conductor?

Given:
R1 = 2 ohms;
R2 = 4 ohms;
I = 18 A;
To find:
I2-?
Decision:
R = R1 * R2 / R1 + R2 = 2 * 4/2 + 4 = 8/6 (Ohm);
U = R * I = 8/6 * 18 = 24 (V);
I2 = U / R2 = 24/4 = 6 (A);
It flows through the second conductor.
