What amount of heat are you sharing in a conductor with a resistance of 15 Ohm for 30 seconds

What amount of heat are you sharing in a conductor with a resistance of 15 Ohm for 30 seconds, if the voltage at its ends is 20V?

These tasks: R (resistance of the taken conductor) = 15 Ohm; t (duration of current passage through the conductor) = 30 s; U (voltage at the ends of the conductor) = 20 V.

The amount of heat that will be released on the taken conductor is determined using the Joule-Lenz law: Q = U ^ 2 * t / R.

Calculation: Q = 20 ^ 2 * 30/15 = 800 J.

Answer: On the taken conductor, 800 J of thermal energy will be released.
