How much heat was released by the conductor in 10 minutes with a resistance of 20 ohms, if the current strength in it is 0.2 A?
| February 7, 2021 | education
These tasks: t (duration of the conductor’s operation) = 10 min (in SI t = 600 s); R (resistance of the taken conductor) = 20 ohms; I (current) = 0.2 A.
The amount of heat released on the taken conductor is determined by the formula: Q = I ^ 2 * R * t.
Let’s make a calculation: Q = 0.2 ^ 2 * 20 * 600 = 480 J.
Answer: The taken conductor should release 480 J of heat in 10 minutes.
