# Determine the work done by the 5.5A current in the dehydrating installation, if the resistance

Determine the work done by the 5.5A current in the dehydrating installation, if the resistance of the oil-water mixture reaches 1200 Ohm, the installation worked for 3s.

To determine the work of the current in the dewatering plant, we apply the Joule-Lenz law: Q = I ^ 2 * R * t.

Values of variables: I – current strength (I = 5.5 A); R – resistance of oil to water (R = 1200 Ohm); t is the operating time of the dewatering plant (t = 3 s).

Let’s perform the calculation: Q = I ^ 2 * R * t = 5.5 ^ 2 * 1200 * 3 = 108.9 * 10 ^ 3 J (108.9 kJ).

Answer: The current in the dewatering plant has done work of 108.9 kJ.
