Insulators
High resistance objects include materials like rubber, glass, and dry wood, while low resistance objects include metals like copper, silver, and gold. High resistance objects impede the flow of electrical current, while low resistance objects allow current to flow more easily.
Too high a resistance is always not a good thing in a circuit. That's what "too high" means.
Air resistance has a greater impact on objects as it opposes the motion of the object through the air, slowing it down. This is especially evident at high speeds where air resistance becomes more significant. Friction tends to have a localized effect on objects in contact with surfaces.

tungsten
The material is called a insulator. It has high resistance to the flow of electric current.
Tungsten is a good conductor with high resistance. It is commonly used in applications that require high resistance to heat and wear, such as light bulb filaments, because it can maintain its structural integrity at high temperatures.
A perfect insulator (which does not really exist) would have an infinitely high resistance. Good insulators provide very high resistance to current flow, on the order of tens of megohms and up.
Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.
No, a good conductor has a low resistance.
Air resistance can be a problem because it creates drag force that slows down objects moving through the air. This resistance can make it harder for vehicles to reach high speeds or for objects to maintain their trajectory. In some cases, air resistance can also generate heat, leading to overheating or damage.
