The two conductors are connected in parallel. The resistance of the first is 3 times less than the second

The two conductors are connected in parallel. The resistance of the first is 3 times less than the second, a current of 3 A passes through the first conductor. What current passes through the 2nd conductor.

1) The same voltage U will fall on both resistances.
Ohm’s law for each of them:
I1 = U / R1;
I2 = U / R2;
R1 = R2 / 3;
R2 = 3R1;
I2 = U / 3R1;
I1 / I2 = (U / R1) / U / 3R1 = 3;
I2 = I1 / 3 = 3 A / 3 = 1 A.
Answer: 1 A.
2) The magnetic field does not act on stationary charges.

Answer: From the side of the field, a force F = 0 acts on a stationary electron.
