Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit.
For instance the flow of current would be different between wood and rubber, both insulators.

Insulators offer resistance to the flow of electric current.?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.
What are the materials that resist the flow of electric charges through them are called?
True..Materials, such as copper or aluminum, that offer low resistance to the flow of electric charge are called conductors.
Do conductors offer very little resistance to the flow of electricity?
Yes- you have suggested a correct working definition for a conductor.
Why do snowflakes float in the air and don't fall faster than raindrops?
Because raindrops are round - snowflakes are flat. Being flat, they offer resistance to the air they're floating in - and thus fall slower.
Does air conduct electricity?
Yes, Air can conduct electricity. There are a lot of conditions to it. An classical example would be lightening. Where the Current, or technically, the electrons flow between the clouds to the Ground. Every elements to an extent conduct electricity, what is more important is the amount of resistance they offer to conduct electricity. But when the Voltage or the pressure for the current to flow, the resistance does break down and allows the current to flow. Search for the term called Break down voltage. Its better to read a nice article rather to look for full explaination here..

Compare conductor and insulator?
Conductors and insulators are different and simalar in many ways.Two ways they are simallar are they both have electrons and have something to do with electricity.Three ways they are different that conductors let heat and electricity go through it .On the other hand insulators do not let heat or electreicity go through it easily.Another way is conductors transfer eelectrons easily but meanwhile the insulator psses on electrons with difficulty.One last thing is that conductors are not current but insulators are current.

How does insulators and resitors and conductor work in a ciriuts?
first of all insulators are better called resistors in circuits. Conductors are in form of wire,and others which allow flow of current. Resistors offer opposition to flow of current delivering controlled amount of electricity.
Why do you we use metal in fuses?
Fuses are designed to carry safe amounts of electrical current and to rapidly break the circuit when current becomes too intense. Metals, because their valence electrons are not constrained, are good electrical conductors. As current is increased, resistance to electron flow causes the metal to heat and then to melt, breaking the electric circuit, and preventing damage to anything other than the fuse. Carbon is also a good conductor. But as current increases and it becomes hot its resistance decreases. So it does not offer protection to the rest of the circuit. Other materials, glass, ceramics, polymers, and semiconductors do not have free electrons and either insulators or poor conductors so they don't work as well in high current circuits.
What are two examples of good insulators?
Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.
What restricts the movement of charges?
From simple to complex. 1. The restriction is resistance: low reistance, small restriction, high resistance, large restriction. 2. Availability of charge carriers: metals have many free electrons, so they convey electric currents well and offer little restriction - low resistance. 3. Scarcity of charge carriers: non-metals (water, wood, rubber plastics, glass) have few free electrons, so they offer large restriction to the attempt to carry an electric current: high resistance. 4. Consider the diameter (cross-section area) of a conductor, and how increasing the area would affect resistance. 5. Consider the length of a conductor, and how increasing the length would affect resistance.
Can a liquid offer resistance to stress?
yes.due to the surface tension ,there is liquid offer resistance.
What doesnt conduct heat well?
Heat insulation is defined as the resistance to the flow of heat offered by a material when it is subject to a change in temperature. Objects that put up a lot of resistance to heat flow don't conduct heat well, and are called insulators. Some examples of insulators are wood, rubber and glass. Things that do conduct heat well don't offer much resistance to heat flow. Many metals fall into this category, such as aluminum, copper, and gold. See the link below for more information on heat conduction.
Do conductors offer very little resistant to the flow of electric current?
Yes- you have suggested a correct working definition for a conductor.
How would you find out the length of the wire effects the voltage drop across the wire when the current passing is kept constant?
A: There are tables that qualify IR drops for wire lenght. All wire do offer resistance to current this current will cause directly a volatge drop according to the wire resistance so it can be measured to find the IR drop
