Question

Using the conduction tester, an object was found that the bulb begins to glow. Is that an object, a conductor or an insulator? Explain. ​

Answer 1

Hint:We are asked if an object is a conductor or an insulator based on a conduction test. To be clearer, we are asked if the bulb begins to glow is that an object, a conductor or an insulator. We can start to attempt this question by defining the terms, conductor, and insulators. We can then move onto what kind of object allows the current to flow so as to make the bulb glow, this can lead us to the solution.

Complete answer:
Let us start by defining the two types of materials (this classification is done based on its capability to conduct electricity). The two types of materials are conductors and insulators.
Conductors:This type of material allows the passage of current through it freely. A conductor allows the motion of charges to be in any direction. Some examples of conductors include metals and semiconductors.
Insulators:This type of material does not allow current to flow through it freely. The atoms in these materials are tightly bound and cannot move. Some examples include paper, wood, and plastics.

Therefore, conductors allow electricity to pass through them however insulators do not and without there being a conductor in place to complete the circuit no electricity would've gotten to the bulb.

Note:Conductors are the materials or substances which allow electricity to flow through them. They conduct electricity because they allow electrons to flow easily inside them from atom to atom. Conductors have the presence of free electrons on their surface. When current is passed through a conductor, these electrons are able to move around freely and thus conduction occurs.
