What amount of heat will be released in 10 minutes by a 1 kOhm resistor if the current in it is 10 mA?

Given: t (resistor operating time) = 10 min (600 s); R (resistor resistance) = 1 kOhm (10 ^ 3 Ohm); I (current in the resistor) = 10 mA (10 * 10 ^ -3 A).

The estimated amount of heat that will be released on the resistor in question is calculated using the Joule-Lenz law: Q = I ^ 2 * R * t.

Let’s perform the calculation: Q = (10 * 10 ^ -3) ^ 2 * 10 ^ 3 * 600 = 60 J.

Answer: Heat will be released on the resistor in the amount of 60 J.
