Question

Приемник за пять суток непрерывной работы израсходовал24 кВт ⋅ ч электроэнергии при напряжении 220 В. Определить ток и сопротивление приемника.

Answer 1

I*U=24000
I=24000/220
I=109A
I=U/r
109=220/r
r=220/109
r=2

Answer 2

Calculation of Current and Resistance

To determine the current and resistance of the receiver, we can use the formula:

Power (P) = Voltage (V) × Current (I)

Given that the power consumed by the receiver over five days of continuous operation is 24 kWh (kilowatt-hours) and the voltage is 220V, we can calculate the current and resistance.

First, let's convert the power from kilowatt-hours to watt-hours:

24 kWh × 1000 = 24,000 watt-hours

Now, we can calculate the current using the formula:

Current (I) = Power (P) / Voltage (V)

I = 24,000 watt-hours / 220V

To find the resistance, we can use Ohm's Law:

Resistance (R) = Voltage (V) / Current (I)

R = 220V / I

Let's calculate the current and resistance:

Current (I) = 24,000 watt-hours / 220V = 109.09 Amperes

Resistance (R) = 220V / 109.09 Amperes = 2.015 Ohms

Therefore, the current flowing through the receiver is approximately 109.09 Amperes, and the resistance of the receiver is approximately 2.015 Ohms.

Please note that the calculations provided are based on the given information and assumptions.
