Determine the amount of heat released on a conductor with a resistance of 150 Ohm, under a voltage of 320 Volts in 4.5 hours
Initial data: R (resistance of the used conductor) = 150 Ohm; U (voltage under which the conductor is located) = 320 V; t (operating time) = 4.5 hours (in SI t = 16200 s).
The heat that is released on the used conductor is determined by the formula (we apply the Joule-Lenz law): Q = U ^ 2 * t / R.
Calculation: Q = 320 ^ 2 * 16200/150 = 11 059 200 J ≈ 11 MJ.
Answer: For 4.5 hours, 11 MJ of heat will be released on the used conductor.
