Question

Сопротивление электрического паяльника 440Ом. Напряжение, при котором он работает, 220В. Определите мощность тока, потребляемого паяльника. Пожалуйста, ДАНО И РЕШЕНИЕ. Спасибо заранее, Господа.

Answer 1

R-440 ом
U-220 в
найти p
решение:
p=U(в квадрате)резделить на R
подставишь если что сама

Answer 2

Calculation of Power Consumed by the Soldering Iron

To determine the power consumed by the soldering iron, we can use the formula:

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

Given that the resistance of the soldering iron is 440 Ohms and the voltage at which it operates is 220V, we can substitute these values into the formula to calculate the power consumed.

Power (P) = 220V / 440 Ohms

Simplifying the equation:

Power (P) = 0.5 Amps

Therefore, the power consumed by the soldering iron is 0.5 Amps.

Please note that the search results provided by You.com did not contain relevant information for this specific calculation. However, the calculation is a basic application of Ohm's Law, which states that the power consumed by a device can be calculated by dividing the voltage across the device by its resistance.
