Calculate the resistance of the power line in Kulsary, which connects the oil rig with the substation

Calculate the resistance of the power line in Kulsary, which connects the oil rig with the substation, if a current of 12A flows in it at a voltage of 380 V.

These tasks: U (effective voltage on the power line) = 380 V; I (the strength of the current that flows in the power line) = 12 A.

To determine the resistance of the power line, it is necessary to divide the effective voltage by the current strength (Ohm’s law for a section of the circuit): R = U / I.

Let’s perform the calculation: R = 380/12 = 13.67 Ohm.

Answer: The electrical line has a resistance of 13.67 ohms.
