Determine the amount of heat that will be released in the conductor in 10 minutes if the resistance of the device is 10 kΩ, and the current in the circuit is 12 A.
Given a device with resistance R = 10 kOhm = 10000 Ohm. From the condition of the problem, it is known that the current in the circuit was I = 12 A, and a certain amount of heat Q was released in the conductor during the time t = 10 min = 600 s. To determine this amount of heat, we use the Joule-Lenz law: Q = I² ∙ R ∙ t.
Substituting the values of physical quantities in the calculation formula, we find the amount of heat that will be released in the conductor:
Q = (12 A) ² ∙ 10000 Ohm ∙ 600 s;
Q = 864,000,000 J = 864 MJ.
Answer: 864 MJ was allocated in the conductor
