Question

Какое количество теплоты выделится в проводнике с сопративлением 1 Ом в течении 30 секунд при силе тока 4 А

Answer 1

Нужно по формуле сила тока в квадрате умноженное на время и на сопротивление когда всё умножили получилось 480дж

Answer 2

Calculation of Heat Generated in a Conductor

To calculate the amount of heat generated in a conductor with a resistance of 1 Ohm, flowing a current of 4 Amps for a duration of 30 seconds, we can use the formula:

Q = I^2 * R * t

Where: - Q is the heat generated in Joules (J) - I is the current in Amperes (A) - R is the resistance in Ohms (Ω) - t is the time in seconds (s)

Substituting the given values into the formula:

Q = (4 A)^2 * 1 Ω * 30 s

Simplifying the equation:

Q = 16 J * 1 Ω * 30 s

Q = 480 J

Therefore, the amount of heat generated in the conductor with a resistance of 1 Ohm, flowing a current of 4 Amps for 30 seconds, is 480 Joules.

Please note that the calculation assumes that all the electrical energy is converted into heat energy in the conductor, and there are no other energy losses or factors to consider.
