Question

Физика помогите: на 2 языкахПровідник з опором 0,012кОм підключено у мережу з напругою 220В. Визначити потужність струму у провіднику.Проводник с сопротивлением 0,012 кОм подключено в сеть с напряжением 220В. Определить мощность тока в проводнике.

Answer 1

N=U^2/R
N=220*220/12=4033,3
или округли 4033
вроде так)

Answer 2

Calculation of Power in a Conductor

To determine the power in a conductor, we can use the formula:

Power (P) = (Voltage (V))^2 / Resistance (R)

Given that the resistance (R) of the conductor is 0.012 kΩ and the voltage (V) in the circuit is 220V, we can substitute these values into the formula to calculate the power.

P = (220V)^2 / 0.012 kΩ

Let's calculate the power in the conductor.

P = (220^2) / 0.012

Using a calculator, we find that the power in the conductor is approximately 4,033.33 watts (W).

Therefore, the power of the current in the conductor is approximately 4,033.33 watts (W).

Please note that the power is given in watts (W) and not kilowatts (kW) since the resistance is given in kilohms (kΩ) and not ohms (Ω).

I hope this helps! Let me know if you have any further questions.
