resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
If they get cold enough, they may change their phase; mainly, from gas to liquid, or from liquid to solid. Also, in most cases materials tend to use up less volume when they are cooled. Other properties also change, such as electrical resistance - one interesting case is superconductivity, where certain materials suddenly have ZERO RESISTANCE below a certain temperature.
The unit for resistance is the Ohm.
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.

Because the main purpose of a toaster is to radiate heat. In order to generate heat from electric current, resistance is required in the circuit.
Superconducting materials.
If you mean zero electrical resistance for an electromagnet, this is possible with superconductivity. This can be achieved for certain materials at fairly low temperatures - typically a few kelvin.
Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.

It is the resistance of insulating material in electrical equipment e.g. electric motors, etc., measured in megohms.Some materials like glass, mica and others are classified as insulators because their resistance to the flow of electrical current is very high.The basic unit of resistance is the ohm. A megohm means a resistance equal to 1 million ohms.

Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
