Initial data: R (value of the resistance of the conductor) = 2 kOhm = 2 * 10 ^ 3 Ohm; U (conductor voltage) = 4 V.
To determine the current in the conductor, we calculate the ratio of the voltage on the conductor to its resistance (Ohm’s law for a section of the circuit): I = U / R = 4 / (2 * 10 ^ 3) = 2 * 10 ^ -3 A = 2 mA.
Answer: The current in the conductor is 2 mA.
