1.transportation of electricity.
2.the making of heating coils?why?
Answer for above question ​

Answer 1

Answer:

1.Power lines or transmission lines, such as those in Figure 1, transport electricity from place to place. Usually, this electricity is alternating current so step-up transformers can increase the voltage. This increased voltage allows efficient transmission for 500 kilometers or less.

2.That's why it's coiled: a coil packs more length (and light) into the same space. ... Inside the glass bulb, there's a very thin coil of wire called a filament. When enough electricity flows through it, it glows white hot, very brightly—so it's really making light by making heat.
