What amount of heat will be released in 2 minutes in a conductor at a current of 0.75 A and a voltage of 36V?

Initial data: t (time of passage of electric current through the conductor) = 2 min; I (current in the conductor) = 0.75 A; U (effective voltage across the conductor) = 36 V.

SI system: t = 2 min = 120 s.

To calculate the amount of heat released on the conductor, we will use the Joule-Lenz law: Q = U * I * t.

Let’s calculate: Q = 36 * 0.75 * 120 = 3240 J.

Answer: 3240 J of heat will be released on the conductor in 2 minutes.
