What type of resistance does a good insulator provide?
A perfect insulator (which does not really exist) would have an infinitely high resistance. Good insulators provide very high resistance to current flow, on the order of tens of megohms and up.
Is there a minimum value of contact resistance of bus bar or value per joints?
You want that as low as possible. Make sure all contacts are clean and if there is high current involved I would suggest a transfer paste. Whatever you decide is the resistance is can help you calculate the voltage drop across the connection and therefore the heat that will be created. You want as little loss there as possible. The resistance will change under load. (increase)
What is excessive electrical resistance?
High resistance means insulation
Why does voltmeter have high internal resistance?
No, ammeters have a low internal resistance. This is so that when they are put in series with a circuit, they change the circuit's operating characteristics as little as possible.Contrast this with voltmeters, which do have a high internal resistance, and which are intended to be placed in parallel with the circuit they are measuring.Use the link below to the related question on why ammeters have a low internal resistance and read through that information to see why things are the way they are.
What is the difference between on and off state resistance?
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
What is ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
Why might you want to use a material with high resistance?
High Resistance Opposes the flow of Electricity that results into production of Heat and Light.
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.

What causes high amps?
High voltage and low resistance would cause high amps. E = I R or I = E/R. PS E would be electromotive force measured in volts. R would be resistance measured in ohms. I would be current flow measured in amps.
Does plastic have a high resistance?
Yes, it has a high resistance as it is an insulator.
Do Dead batteries have high internal resistance?
yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high resistance.
Would cause high resistance in a closed electrical circuit?
corroded/dirty connections
If a volume knob has high resistance is the radio's volume loud or low?
If a volume knob has a high resistance, then the radio's volume would be low because more of the electrical signal would be resisted and not reach the amplifier and thus not reach the speakers.
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
What is high resistance what is low resistance?

How high is your body resistance?
Your body resistance is high- hard to push electrons through.
