Here's a breakdown:

* Resistance: This is the property of a material that hinders the flow of electric current. Think of it like friction for electrons.

* Resistivity: This is a specific property of the material itself, independent of its shape or size. It tells you how much the material resists current flow.

* Resistors: These are components designed to have a specific resistance. They are used in circuits to control the flow of current.

Examples of materials with high resistance:

* Insulators: These materials have extremely high resistance, practically blocking all current flow (e.g., rubber, glass, plastic).

* Some metals: While many metals are good conductors, some have higher resistance, like tungsten used in light bulb filaments.

* Semiconductors: These materials have resistance between conductors and insulators, making them useful in electronics (e.g., silicon, germanium).
