There is no more the dielectric constant for insulators than the colour for shirts.
Every shirt has a colour, and every insulator has a dielectric constant.
Find out what material your insulator is, then look in Kaye & Labey or any good handbook for radio and electronics engineers.
Insulator keep us from electric shocks because if we get shocked we will die.
Electric insulators
In electricity, Insulators help insulate electric charges. Conductors conduct the electric charges and make them into electricity.
Not really, insulators simply cannot support the passage of an electric current.
Curt Brinkmann has written: 'Die Isolierstoffe der Elektrotechnik' -- subject(s): Electric insulators and insulation
Insulators do not allow electric current to flow through. Conductors allow electric current to flow through.
Materials that do not allow electric currents to pass are called insulators.
rubber, wood. etc, insulators
Insulators
because electricity cant travel through them
insulators.
Insulators [spelling] slow the flow of energy, either heat of electric.
