Do electric conductors block electricity?
NO! Although its no, every conductor has resistance that blocks little current and dissipates in the form of heat. Its negligible in conductor. Eg: silver has lowest resistance compared to iron

Yes- you have suggested a correct working definition for a conductor.
What makes an object conductor?
A conductor has low electronegativity and has 3 or less electrons in the outer shell of the atom. Conductors let electrons run through them with little to no resistance.
What is an electrical resistor?
When an electric current moves through a conductor, there is always some electrical resistance to the current. This is because of the attraction of the electrons to the positive nuclei of the atoms in the conductor. This attraction is greater in some conductors than in others, giving them a greater electrical resistance.As the electrons are pushed through a conductor they lose some of their energy as heat. This waste heat can be a nuisance; for example, computers get hot when used. However the waste heat is sometimes useful. For example, because nichrome wire has a fairly high resistance, it is used to make the heating elements in many electrical appliances used around the home. It is usually coiled to take up less space. The filament of a light bulb is made of very thin tungsten wire. When a current is passed through it, the wire becomes so hot that it gives off a brilliant white light.Hope that answers your question!!Thanks for reading :)Thanks GeorgeElectrical resistance exacts a voltage drop as the price for allowing electrical current to flow through the resistance. The use of the term resistance implies that the current flow will be in phase with the voltage across the resistor and that the current flow will be proportional to the voltage drop. These conditions are Ohm's Law. There are devices which do not meet these conditions. They can be useful, but they should be considered as another component class such as thermistors etc. Mathematically V = I x R, where V is the instantaneous voltage across the resistance, I is the instantaneous current through the resistance, and R is a constant specific for the resistance. If V is in Volts and I is in Amperes, then R will be in Ohms. Practical resistors vary modestly with temperature, but change very little with voltage or current, except as these change the temperature. A resistor should be the same for flow in either direction and for DC and AC of modest frequency. At high frequencies resistors can display inductance and/or capacitance.Resistors can be purchased with various resistance tolerances, with various temperature sensitivities, and with various power ratings. Running at full power rating may shorten life and may produce temperatures which affect adjacent components. Derating to 1/2 or even 1/3 power may be wise.It is a measurement of how hard electricity flows thru specific area. In SI is measured in ohm.Resistance is the opposition to the flow of electric current, and is measured in ohms. Resistance is directly proportional to the length of a conductor and inversely proportional to its cross-sectional area, and directly proportional to the resistivity of the material from which the conductor is manufactured. As resistivity is affected by temperature, resistance is indirectly affected by temperature.An example of an electrical resistance is a bar-type radiant heater. The resistance in the windings (these are usually of small diameter wire) causes the electrons to flow slower, causing heat which manifests itself as the hot glow you see and the warmth you feel.
What is lost volts?
A battery is rated to supply a certain number of volts. However, it actually supplies less, because they are "lost" as the current has to get out of the battery in the first place.(The battery has internal resistance)The amount of lost volts depends on the current being drawn:The less resistance a circuit has, the more current is drawn, because it's easier to flow.Example:If the circuit has little resistance, it draws a large current and the battery's internal resistance causes more lost volts.If the circuit has high resistance, it draws a small current and there are fewer lost volts.This is why when you short-circuit a battery (give it hardly any resistance to go through) it heats up and may explode. A large current is drawn and all the volts are used by the battery's internal resistance.

What is an electric conductor and insulator?
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
What is an electric circuit with little or no resistance?
A: As current approaches infinity on a device it is known as a current source.
Do conductors offer very little resistant to the flow of electric current?
Yes- you have suggested a correct working definition for a conductor.
Do conductors do energy transformation?
They should not, but in real life conductors transform some energy and this is called "loss". E.g., electric wire heats up when the current runs through it, a little bit of electricity is lost (due to wire's resistance) in form of heat. Transformation of energy should be kept as low as possible since any transformation in a conductor is unwanted.
What is the term for an electric charge that does move?
That is called an electric current. Actually, defining an electric current as a "movement of charge" is a little simplistic, but movement of charge is certainly an important part.That is called an electric current.

What is a material that allows electron to flow easily or with little resistance?
Those are the materials we loosely call "conductors".

How the current in a circuit changes if the resistance increase and the voltage remains constant?
If the resistance increases, the current diminishes. The voltage may drop a little and the multimeter can't read it or can't accuse so little voltage dropping.
What is a material with little resitance to electric current called?
This is called a conductor.
What is meant by skin effect?
The skin effect occurs in conductors carrying alternating currents, where the tendency is for the current to flow towards the surface of the conductor. The effect increases with frequency. At radio frequencies, the skin effect is so pronounced, that there is little point in using solid conductors, so tubes are used instead.The skin effect is responsible for the so-called 'AC resistance'. This is because the skin effect acts to reduce the effective cross-sectional area of a conductor, thus increasing its resistance compared to when a DC current passes through the conductor.
