What is the voltage across a resistance of 54 ohms, if, when a current passes for 10 minutes, an amount of 2000 kJ is released on it.

These tasks: R (considered resistance) = 54 Ohm; t (duration of current passage) = 10 min (600 s); Q (the amount of heat released on the resistance) = 2000 kJ (2 * 10 ^ 6 J).

The voltage that was applied to the resistance under consideration can be expressed from the formula: Q = U2 * t / R, whence U = √ (Q * R / t).

Calculation: U = √ (2 * 10 ^ 6 * 54/600) = 424.3 V.

Answer: The resistance in question will need to be supplied with a voltage of 424.3 V.
