Question

Длина медного провода используемого в осветительной сети 100 м площадь поперечного сечения его 2 кв мм чему равно сопротивление такого провода

Answer 1

R=Pl/S=0.017*100/2=0.85Ом

Ответ: 0.85Ом

Answer 2

Length of the Copper Wire:

The length of the copper wire used in the lighting network is 100 meters.

Cross-Sectional Area of the Wire:

The cross-sectional area of the wire is 2 square millimeters.

Resistance of the Wire:

The resistance of the wire can be calculated using the formula:

Resistance = (Resistivity x Length) / Cross-Sectional Area

To determine the resistance of the wire, we need to know the resistivity of copper. However, the provided search results do not contain the necessary information to calculate the resistance.

I apologize for the inconvenience, but without the resistivity value, I am unable to provide the exact resistance of the wire.
