Does Vietnam have electricity?
Today Vietnam has electricity. In cities and even villages the Vietnamese population has access to electricity to run their fridges, televisions, air conditioners and computers. If you travel to Vietnam, look up. The electrical wires that are strung from pole to pole are a mass of black cobwebs, tangled webs of wire that are a fire-fighter's/electrician's nightmare. Blackouts are somewhat common due to hurricanes or government mandates in an effort to cut back usage in the summer. Vietnam has one of the fastest growing economies in the world and accessing electricity whether legally or illegally is not an issue for most.
What must a 'wire' be?
A wire is usually a cylindrical length of copper. Its cross-section area has to be about 1/8 sq. mm for each amp of current it has to carry, for normal thin wires that carry currents up to about 30 amps for no more than 2 hours per day. Wires that are too thin waste energy, and in excessive cases can overheat.
How did Thomas Edison's light bulb work?
Electricity goes through the "electrical foot contact", heats up the wires (connected to the tungsten filament) therefore lighting the light bulb up. The filament is supported by wires. The glass mount holds up the two wires connected to the filament. That is how I think the light bulb works. Have a look.
