∙ 9y agoHaving high resistance is bad. It is like a hose that is plugged into sand. The sand will stop the easy flow of water, this is like high resistance.

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.
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.
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.
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.
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
List of good and bad conductor of electricity?
Good conductors conduct electrical current very easily because of their free electrons. Some common good conductors are copper, aluminum, gold, and silver.Bad conductors (or insulators) oppose electrical current and make poor conductors. Some common insulators or bad conductors are glass, air, plastic, rubber, and wood.Conductors have a very low resistance to electrical current while insulators or bad conductors have a very high resistance to electrical current.
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.

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

If you are using a multimeter as an ohmmeter and you get a reading of maximum resistance what does that tell you about the circuit you are measuring?
Did you mean "maximum RESISTANCE" or "maximum VALUE"? If the former, then, you have a ZERO reading, meaning there is high resistance, and no electrical connectivity. If the latter, you have a ONE (or 100%) reading, meaning there is NO resistance, or absolute electrical connectivity. As an analogy, if you turn on a plugged-in, working, lamp, then it has NO resistance, such that power flows easily through the cord; if it didn't turn on, then there IS resistance, such that no power flows, possibly due to broken wire, bad switch, burned-out bulb, or blown fuse.
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 are some good conductors and bad ones?
Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
