Final answer:
Glass, rubber, and paper act as insulators because they don't allow charge carriers to move freely, making them effective in preventing electrical conduction.
So, the correct answer is: Insulators
Step-by-step explanation:
Glass, rubber, and paper are all examples of insulators. In the context of electricity, an insulator is a material that does not allow charge carriers, typically electrons, to move freely through it.
The charges in insulators are bound to the atoms and do not move easily, which is why materials such as rubber and glass are used to protect against electrical currents and prevent conduction.
In contrast, metals are examples of conductors which have low resistance and allow for easy movement of charge. Semiconductors, like silicon and germanium, have properties that are intermediate between those of conductors and insulators, and they are used extensively in electronics.
Glass, rubber, and paper are all examples of insulators. Insulators are materials that do not allow charge to move through them easily. Unlike conductors, which allow charge to move freely, insulators restrict the flow of charge.
