Why insulators should always be kept dry?
so it won't conduct current :D
Why do you need insulators?
An insulator prevents electricity from flowing because it has an extremely high resistance.An insulator must never be allowed to get any water on it as the water will conduct electricity!Because they don't allow electricity to pass through them, insulators are hardly ever used "in" circuits as such.Most times insulators have to be used to stop electricity from flowing:where it is not wanted - for instance between two wires in a cable orwhere or it would be dangerous to allow electricity to flow. For instance an electrical appliance such as an oven, water heater or clothes dryer has lots of metal parts inside it and someone could easily get killed (electrocuted) if the current from one of the "live" or "hot" wires inside it was allowed to get to its outside metal casing.So two of the most common uses of insulators are as:jackets or "coatings" for wires and for"bodies" or "cases" of things such as electric plugs, televisions, etc.Another very important use of insulators is to make "circuit boards" on which electrical components can be mounted.By using an insulator for a circuit board means that - as long as it always stays dry - there will usually be no risk of the circuit board shorting out the components by conducting electricity between their terminals.Think of your sink. The outside of the pipe is your insulator. The inside of your pipe conducts the water. You turn on the water. If you did not have the outside of the pipe to insulate the water, it would go all over the place. Instead, it directs your water into your sink. Then when you are through with it, it goes down a drain. That has another pipe. If that pipe was not there, it would go all over the floor and you would have a mess. Electricity works basically the same way.A circuit uses conductors to take the electricity where you want it to go. It uses insulators to keep the electricity in the conductors just like pipes keep water inside them. They take the electricity to where it will do the work and then back to where it came from. It works like your plumbing system.
Short circuits are dangerous because?
electricity always "wants" to take the easiest route, this is the route with the least resistance, this is why an insulator does not conduct electricity, it takes to much force for the electricity to travel through. a short circuit is when the easiest route is the wrong route i.e. the body of a lamp rather than the wiring of the lamp. the danger of a short circuit is dependent on the voltage and current of the electricity.
When is too high a resistance not a good thing in a circuit?
Too high a resistance is always not a good thing in a circuit. That's what "too high" means.
What is a complete conducting path along which electrical charges can flow?
Electrical charges are of 2 types:-Electrons, andIons.A complete conducting path is like a loop which is followed by these charge carriers and then they return back to their original point of starting the flow. A closed electrical circuit is an example of a complete conducting path. In solid conductors electrons are the charge carriers while in liquids the ions are the charge carriers.

So that it's nice!
Are marshmallows insulators or conductors?
Yes, most certified electricians use candy bars to insulate high voltage power lines. If you look at the wires on high grade medical equipment you will notice they are always insulated with the finest candy bars.
Are scissors conductors or insulators?
Depends on what they're made of, not what they are.Anything made of a conducting material is a conductor, whatever it is.Anything made of an insulating material is an insulator, whatever it is.Material properties - conducting or insulating - is more important than shape.Scissors are generally - but not always - made of metal.And metals are usually conductors, making the scissors conductors.But a scissor might have plastic handles. Plastic is usually an insulator, which would make the handles insulators.
Can you give a list of conductors and insulators?
conductors: (items that electricity/energy can flow (better)) copper, gold, metal, iron, steel, coins, (pennies, nickles, dimes, quarters, loonies, and toonies) brass, alligator clips and etc...(you can always search on a different website)
Why insulators should always be kept dry?
so it won't conduct current :D
Is it true the mosque is always having covered by covered?
no
What are materials that allow electrons to move through them easily?
A conductor. Most metals are conductors-they enable electrons to move freely through them, carrying an electrical charge. Most non-metals (notably excluding graphite, an isotope of carbon) are insulators which means that they do not allow an electrical charge to be carried through them.
Good conductors of electricity are often good conductors of heat?
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Is a switch needed to make a circuit work?
Not always. Depends on the circuit.
Every short circuit is always a closed circuit while every closed circuit is not a short circuit?
Long winded but true.
Do static electricity not allow electricity to pass through?
Sorta ... static electricity always develops on insulated things : either non-conductors or isolated conductors.
How would a ammeter be connected in a circuit?
An ammeter is always connected in series in the circuit.
