Resistors and conductors are actually two sides of the same story.
They both conduct electricity and they both resist conducting electricity.
The difference is how well they conduct electricity.
Copper, Silver and Aluminum are examples of brilliant conductors. They resist very little.
Coal-fibers and various metal oxides are examples of poor conductors. They resist much more and falls into the category of being a resistor.
The comparison can easily be made with a water pipe-line.
A huge dimension can carry a lot of water (This is electrical current). It can also contain high pressure (In this analogy, that would be Voltage)
A very small dimension can not carry much water at all (The current is limited. This is what physically happens in a resistor.)
The water pressure is the same, then the big pipe might fill a bathtub in 30 seconds where as the small pipe would maybe need 10 minutes or more.
It works "exactly" the same way with electric components as conductors and resistors.
Some people claim that a conductor is the opposite of a resistor.
This is a wrongful interpretation although it seems to make sense...
They are both conductors of voltage (water pressure as an analogy).
A resistor only limits the current, Amount of water in previous analogy, somewhat, this depending on the specifications of the resistor.
A conductor is a good leader of the electricity and a resistor is damping the electricity.

How is a resistor different from a fuse?
A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
Why neatural ground resistor using in 33kv transformer?
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.
The voltage drop in each resistance is?
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
Why resistor is an electronic device?
electronic circuits are those which deals with flow of electrons. in general electronic devices are categorized based on the flow of e as conductor, insulator and semiconductor. since resistor resists the flow of electrons (it deals or works with electrons), it is consider as an electronic device.
