What amount of heat will a conductor with a resistance of 40 Ohm release in 10 s at a voltage in the circuit of 100 V?

These tasks: t (duration of the taken conductor) = 10 s; R (resistance) = 40 ohms; U (voltage in the circuit) = 100 V.

To calculate the heat that the taken conductor will release in 10 seconds of operation, we use the Joule-Lenz law: Q = U ^ 2 / R * t.

Calculation: Q = 100 ^ 2/40 * 10 = 2.5 * 10 ^ 3 J = 2.5 kJ.

Answer: For 10 seconds of operation, the taken conductor will release 2.5 kJ of heat.
