Determine the work done by a current of 5.5 A in the dewatering unit if the resistance of the oil-water

Determine the work done by a current of 5.5 A in the dewatering unit if the resistance of the oil-water mixture reached 1200 Ohm and the unit was running for 3 s.

Initial data: I (current in the dewatering plant) = 5.5 A; t (operating time of the dewatering plant) = 3 s; R (resistance of a mixture of oil and water) = 1200 ohms.

The work that the electric current will perform under the given conditions is determined by the formula: A = I ^ 2 * R * t

Let’s perform the calculation: A = 5.5 ^ 2 * 1200 * 3 = 108 900 J.

Answer: Electric current will do the work 108,900 J.
