Question

4. За 1,5 минуты в проводнике, при напряжении 0,08 кВ установился ток, силой 3,5 А. Какую работу совершил ток за это время? Чему равна мощность тока? Сколько тепла выделяет проводник за это время? ​

Answer 1

Ответ:

A=I*U*t;A=3,5*80*90=25200Дж.

P=A/t;A=25200/90=280 Вт.

Answer 2

Electric Work, Power, and Heat Calculation

To calculate the work done by the current, we can use the formula:

Work (W) = Voltage (V) × Current (I) × Time (t)

Given: - Voltage (V) = 0.08 kV = 80 V - Current (I) = 3.5 A - Time (t) = 1.5 minutes = 1.5/60 hours = 0.025 hours

Let's calculate the work done by the current: Work (W) = 80 V × 3.5 A × 0.025 hours

Work (W) = 80 V × 3.5 A × 0.025 hours = 7 J.

The power of the current can be calculated using the formula: Power (P) = Voltage (V) × Current (I)

Power (P) = 80 V × 3.5 A = 280 W.

To find the heat produced by the conductor, we can use the formula: Heat (Q) = Power (P) × Time (t)

Heat (Q) = 280 W × 0.025 hours = 7 J.

Therefore, the work done by the current is 7 J, the power of the current is 280 W, and the heat produced by the conductor is 7 J.
