Answer 1

Ответ:

Объяснение:

t = 18 мин = 1080 с

U = 224 B

I = 3,63 А

A - ?

=============

Работа тока:

A = U·I·t = 224·3,63·1080 = 812 851,2 Дж   или   ≈ 813 кДж

Answer 2

Calculation of Work Done

To calculate the work done in moving charge in an electric motor, we can use the formula:

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

Given: - Voltage (V) = 224 V - Current (I) = 3.63 A - Time (t) = 18 minutes

First, let's convert the time from minutes to seconds: - 1 minute = 60 seconds - Therefore, 18 minutes = 18 x 60 = 1080 seconds

Now, we can calculate the work done using the formula mentioned above:

Work (W) = 224 V x 3.63 A x 1080 s

Calculating the value: - Work (W) = 224 x 3.63 x 1080 = 839,923.2 Joules

Rounding the answer to the nearest whole number, the work done in moving charge in the electric motor is approximately 840,000 Joules.
