why are insulators wrapped around electric conductors?

Answer 1

a few reasons

i) safety
ii) to prevent loss of current/power

so insulators are used to prevent the electricity flowing into the environment - which could be adjacent materials (such as you, the walls, the earth...)

wires in your house are insulated because you might touch them, and they light touch other materials resulting in shocks, fires.....
wires that bring the electricity to your town on high pylons are not insulated - instead they us the gap between the insulators to prevent 'conduction betweent he conductors. only the places where the wires attach to the pylons are insulated.
if you have underground electricity supply to your house the wires are insulated as otherwise the electricity will flow inot the damp ground.

an insulator is a barrier to current flow (whereas a conductor does not significantly impede the current flow) the difference is that conductors have a low resistance to current flow. Most insulatros can more be thought as blocking current flow entirely - although they do have the potential to breakdown - which is when you see the arcing.

Answer 2

Just to prevent electricity from flowing out of the sides of the conductor.

Answer 3

To prevent the leaking of electric current.

Answer 4

To prevent arcing of current to ground. To prevent arcing of current through someone or something to ground. And to prevent arcing between hot and neutral.

More to the point, to prevent shorting of any current at all.

Answer 5

to stop u getting electric shock if u touch them
