Answer the followingwhich of them is used in :1.transportation of electricity. 2.the making of heating coils?why?Answer for above question ​

Answer»

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.
