What amount of heat was released in the relstat, the resistance of which is 6 Ohm, if an electric charge of 600 C passed through it in 5 minutes.
Task data: R (rheostat resistance) = 6 Ohm; t (duration of passage of electric current through the rheostat) = 5 min (300 s); q (electric charge) = 600 Cl.
The released amount of heat on the rheostat is determined by the formula: Q = I ^ 2 * R * t = (q / t) ^ 2 * R * t = q ^ 2 * R / t.
Calculation: Q = 600 ^ 2 * 6/300 = 7200 J (7.2 kJ).
Answer: 7.2 kJ of heat was released on the rheostat.
