When electricity travels long distances it is better to have it at higher voltages?

when transmission we usually use high voltages becoz at higher voltages current is less(p=vi,voltage is inversly proportional to current at constant power) so that we can minimize copper losses i2R losses.

For any given load, the higher the supply voltage, the lower the resulting load current. High voltages, therefore, are necessary for the load currents to be low enough to be able to use conductors of practical size and weight (and economy), to ensure low values of voltage drop along the transmission lines, and to limit the line losses.

Why do some electrolytes give better voltages than others?
because they re-act better to electricity
Why does electricity flow through aluminum foil better?
It flows through aluminum foil better because electricity flows throw aluminum or metal better then plastic or other
Does copper conduct electricity better than stainless steel?
Yes. At normal temperatures copper conducts electricity better than almost any other metal; silver is slightly better.
Is warmer or colder water a better conductor of electricity?
warm
Is glass a conductor or insulator of electricity?
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.

How well does sound travel through water?
Sound travels through water much better than it travels through air. In air, sound travels at about 330 m/sec (metres per second). In seawater it travels at about 1,490 m/s (better 1.49km/sec). Sound also travels much further through water than it does though air. This is the way humpback whales can communicate over very long distances with their singing.
When electric from a battery travels straight continuous line what is it considered?
You need to word the question better. Electricity derived from a battery is always DC as batteries are a DC power source.
Why is hydroelectricity better than normal electricity?
hydro electricity is better than normal electricity because it is cheaper.
Does sound travels better through water than wood?
Sound travels better through wood than water
Is water a better conductor of electricity then silver?
no, water is NOT a better conductor of electricity then silver
Why is the national grid system better than each town having its own supply?
Because then every town has the same voltage: before, if there was a sudden demand for electricity in one town- nearby towns couldn't help for they had different voltages. So, the town couldn't cope with the electricity demand but now it can because of the National Grid.
Is nuclear better than electricity?
nuclear is a type of electricity
What is the meaning of proverb 'who travels fastest who travels alone?
you get things done better when you do them without help
What kind of energy travels through water better than through air?
what kind of energy travels through water better than air
How can polymers be used in optical materials?
Over short distances. Glasses work better over long distances.
Is it true that sound wave can travel only through air?
The criteria for sound to travel is presence of particles, sound can't travel in vacuum, it can in air, it can travel even better in water (you can hear roar of whales for huge distances), for example it can travel even better in metal (when you put your ear on a train rail, you can hear train from huge distances.) or just in steam (sound travels better in fog than in clear air, because water in the air is making the air thicker.)
