Determine the amount of heat released in the conductor in 0.5 hour, if the current strength is 0.1A, and the resistance of the conductor is 20 ohms.
Given: t (duration of heat release by the conductor) = 0.5 h (30 min, 1800 s); I (current) = 0.1 A; R (resistance of the taken conductor) = 20 ohms.
The amount of heat released in half an hour on the conductor is determined by the Joule-Lenz law: Q = I ^ 2 * R * t.
Calculation: Q = 0.1 ^ 2 * 20 * 1800 = 360 J.
Answer: 360 J of heat will be released on the conductor in half an hour.
