It is known that when current passes through a conductor, it heats up. What amount of heat is released

It is known that when current passes through a conductor, it heats up. What amount of heat is released in 3 minutes in a conductor with a resistance of 20 Ohm, when such a force of 2 A passes through it?

To find out the heat received from the presented conductor, consider the formula (Zn Joule – Lenz): Qx = I2 * R * t, where I is the passing current (I = 2 A); R is the resistance of the presented conductor (R = 20 Ohm); t – time interval (t = 3 min = 180 s).

Let’s perform the calculation: Qx = I ^ 2 * R * t = 2 ^ 2 * 20 * 180 = 14.4 * 10 ^ 3 J.

Answer: 14.4 kJ of heat will be received from the presented conductor.
