A resistor is really anything that uses electricity along an electric circuit, for example a light bulb, a computer, a radio, etc.

Nothing happens to the resistor other than it may interact with the other components so as to perform a desired function.
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.
It slows down the speed of the electrons , which are all passing through the resistor

A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
the function of a resister is to lower the voltage.
To limit the current

To limit the current
Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
The first 3 band on a resistor indicate the value of that resistor.
