There may be a crack in the ceramic. Also, all insulating materials have a dielectric breakdown voltage, often expressed in volts per mil (0.001 inch). For example barium titanate ceramic breaks down at 75 volts per mil. Thus a 0.5 inch thick insulator of barium titanate ceramic will withstand up to 37,500 volts.

Difference between a semiconductor and insulator?
The difference among Metal,Semiconductor and Insulator is written bellow-1.Metal:Substances through which electricity can pass easily is called Metal.1.Semiconductor:Substance which conductivity lies between Metal and Insulator are called Semiconductor.1.Insulator:Substances through which electricity can not pass easily are called Insulator.
Material through which a current cannot pass or easily flow?
Insulator. Like wood.
What does an electrical insulator do?
An electric insulator blocks the flow of electrons, stopping electricity from flowing. Some examples of electric insulators are plastic, fiber glass, rubber, and wood.CommentAn insulator doesn't actually 'block the flow of electrons'. It simply doesn't have sufficient free electrons available to support an electric current through itself.
What type of burns are the result of current flowing through and exiting the body?
electrical burns
What is the purpose of insulator in overhead transmission line?
Overhead lines are uninsulated, as they depend upon the air to provide insulation. However, they must still be insulated from the towers or poles from which they are suspended. This insulation is provided using glass or ceramic insulators. The greater the line voltage, the longer the ceramic insulator, or the greater the number of glass insulator 'dishes'.
What is a good insulator?
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.
How do electrical insulators help people?
The insulator I refer here is the insulation on the wiring and this helps any in not passing current through them
Does not let electrical currents flow through it?
Insulator.
Why current cannot pass through a insulator?
Insulators are made of non conductive materials and that is the point. Insulators are used to prevent electrical current from leaving the circuit being utilized.

Why does a ceramic bowl keep soup hot longer than a stainless steel bowl?
Ceramic is an insulator, where stainless steel is a conductor of heat. Heat transfers more rapidly through stainless steel than through ceramic.
What a good insulators?
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.
Can a electric current run through ceramics?
There are certain ceramics (e.g. barium-copper-oxide ceramics) that become superconductors when cooled in liquid nitrogen. But at higher temperatures these ceramics are insulators like any other ceramics.
An electrical insulator has what?
In case of electrical insulator the electrons are tightly bound to the nuclei of the atoms and no free electrons are available. In reality free electrons are the carriers of electrical charges through the conductor. As free electrons are not available then current becomes zero for even little bit high voltages. Glass, mica, rubber are examples.
What do you call a material that does not allow electricity to pass through it?
An electrical "insulator".
Material through which a current cannot pass or easily flow?
Insulator. Like wood.
Are materials that electrical current cannot pass through?
Any material that electricity can't pass through is classed as an insulator. Examples of insulators are glass, ceramics, plastic, dry wood, and so on.
