How much energy will be released in a conductor with a resistance of 12 ohms in 10 minutes if connected to a network with a voltage of 120 V?
Task data: R (resistance of a given conductor) = 12 Ohm; t (duration of conductor operation) = 10 min (in SI t = 600 s); U (mains voltage) = 120 V.
The energy that will be released in the conductor is calculated by the formula: Q = U ^ 2 * t / R.
Let’s calculate: Q = 120 ^ 2 * 600/12 = 720 * 10 ^ 3 J (720 kJ).
Answer: For 10 minutes of work, 720 kJ of energy will be released in the conductor.
