How much heat will a 50 Ohm resistor release in 10 minutes if the current in the circuit is 5A?
| June 11, 2021 | education
Initial data: t (time of passage of electric current through the resistor) = 10 min = 600 s; R (resistor resistance) = 50 ohms; I (current in the circuit where the resistor is connected) = 5 A.
The amount of heat that the resistor will release can be determined by the formula: Q = I ^ 2 * R * t.
Let’s calculate the resistance of the resistor: Q = 5 ^ 2 * 50 * 600 = 750,000 J or 750 kJ.
Answer: In 10 minutes, the resistor will release 750 kJ of heat.
