What is the characteristic of a material that hinders electron flow?
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
Is 8 ohms good or bad resistance?
For an 8 ohm speaker, 8 ohms is perfect. "Good" and "bad" are relative to the application.
What is transistor checker?
A: Any VOHM can check a transistor but only as good or bad .It will never tell you how good or how bad. A TEKTRONIC curve tracer does a very decent job for these devices.
How do you use bentonite in electrical grounding?
Bentonite has an affinity for water. By packing Bentonite around the ground rod it increases the conductivity of the ground rod. Ground rods are not supposed to have a resistance above 5 ohms when compared to the utility's ground grid. Getting the ground rod into this resistance zone in bad soil conditions is aided by the use of Bentonite.
Is mica an electrical insulator?
Mica has such poor electrical conductivity that it has often been used as an insulator. The resistivity of mica ranges from 1x10^12 to 2x10^14 Ω/cm depending on the type of mica. For reference, copper, a good conductor, has a resistivity of only 1.68×10^−8 Ω/m or 1.68x10^-10 Ω/cm. no, it is an insulator.
Is rubber a bad insulator?
Rubber is actually a good insulator due to its high resistance to the flow of electricity. It is commonly used in electrical cords and cables to help prevent electrical shocks and short circuits.
What is a bad connection in an electrical circuit called?
"A wiring fault" which - depending on the actual behavior of the bad connection - might also be described as "an intermittent fault", "a high resistance fault", or a combination of all three terms. For example: "An intermittent, high resistance wiring fault".
What are the electrical properties?
good conductors of heat bad insulators low resistence high conductivity
What are bad conductors known as?
Bad conductors are known as insulators. They have high resistance to the flow of electricity and are commonly used to prevent the passage of electrical current. Examples include rubber, glass, and plastic.
Why is air resistance bad?
Air resistance is neither good nor bad, it is simply a factor. Air resistance costs us in terms of performance, a car with high wind resistance gets lower mileage than one with less; but without air resistance planes would not fly at all.

Why is nichrome used for heating element in a toaster?
A nichrome wire has high resistance and gets heated faster, saving electricity.
What are four bad conductors?
Rubber, wood, plastic, and glass are examples of materials that are poor conductors of electricity. These materials have high electrical resistance, preventing the flow of electricity through them.
Is any metal good conductor of heat but bad conductor of electricity?
Dear Asker,Is this a personal question? I believe it is. There is no metal that is a good conductor of heat but bad conductor of electricity. Why? Its because both conductive properties in metals comes from the reason that metals have free/mobile electrons. The more mobile electrons you have, the better conductor you are. Copper have a heat conductivity of 400 W/(m.K) while it have a electrical resistance of 1.68×10−8 ρ (Ω•m). It has high heat conductivity and low electrical resistance, just second to silver, which have a heat conductivity of 430 W/(m.K) while it have a electrical resistance of 1.59×10−8 ρ (Ω•m).sincerelyJet
Is electrical conductivity as a liquid good or bad?
It depends on the context. High electrical conductivity in liquids can be good for efficient transmission of electricity (as in electrolytes or conductive solutions), but it can also be bad if it poses a safety hazard (such as in the case of spilled water near electrical devices).
What does Good electrical insulator mean?
A good electrical insulator is a material that does not conduct electricity easily. It has high resistance to the flow of electrical current, so it helps prevent the leakage or dissipation of electrical energy. Examples of good electrical insulators include rubber, glass, and plastic.
