In what particular situation are you considering this term? In general, the length of the cable line is the length of the cable from the source of electricity to consumers. For example, from a transformer substation to a specific consumer.
and if on a simple basis, let’s say an electric kettle for 10 meters of cable 2.5 consumes 2 kW, and if the cable is 20 meters long then the kettle will consume more? and how to determine this?
and how much should I multiply? or add? let's say 10 meters 15 A, 20 meters 30 A, that is, two times, the loss in two is less, I do not understand these formulas at all

Well, let's say from the apartment reading to the outlet, that is, the longer the length, the greater the resistance? I can’t understand something
That's right.

Download the special cable v2.1 program, in it you can make an accurate calculation.
