20KV can throw a spark about a centimeter long in dry air.
the distance at other voltages is directly proportional to the voltage. you should be able to calculate the distances for other voltages yourself from this info.
It can travel in many different ways it can be through a wire or other many conductors
Yes, electricity can travel through mineral water because of the presence of ions.
No.
electricity always wants to travel through to complete the circut
electricity can travel through anything with a positive and negative electrical charge
Yes
Yes it does
Yes, aluminium conducts electricity.
Electricity can travel throughout freely moving Electrons, like in metal which is in wires under the rubber.
Before electricity, the most advanced form of travel was the horse and buggy. Now, we are able to travel through the air and through the sea at much greater speeds
yes. At its powerfullest, electricity can travel through anything, like lightining through the air
a circuit.
