Answer 2

В данном случае нужно найти работу.

A = I * U * t = 220 * 550 * 12 * 3600 = 5227 МДж ))))) Оч много))))

Answer 3

Calculating Energy Consumption of a Trolleybus

To calculate the energy consumption of the trolleybus for a 12-hour shift, we can use the formula:

Energy (in kilowatt-hours) = Power (in kilowatts) × Time (in hours)

First, let's calculate the power consumption of the trolleybus using the given current and voltage.

Calculating Power Consumption

The power consumption of the trolleybus can be calculated using the formula:

Power (in kilowatts) = Current (in amperes) × Voltage (in volts)

Given: - Current = 220 A - Voltage = 550 V

Using the above values, we can calculate the power consumption of the trolleybus.

Power = 220 A × 550 V

Power = 121,000 W = 121 kW

Calculating Energy Consumption

Now, we can calculate the energy consumption of the trolleybus for a 12-hour shift.

Energy = Power × Time

Energy = 121 kW × 12 hours

Energy = 1,452 kWh

Therefore, the trolleybus consumes approximately 1,452 kilowatt-hours of energy during a 12-hour shift.
