Write a short paragraph about electrical current using the terms conductor and insulator.

Answers

Answer:

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants

Answers

I think it is water vapor since condensation is the process of water vapor going back to liquid water.

Clouds and fog are water features often associated with condensation. The correct option is C.

The process by which water vapour, a gaseous form of water, changes into liquid water is called condensation.

When warm, moist air meets a cooler surface or when the air itself cools, it happens. As a result of this cooling, water vapour loses energy and condenses into tiny water droplets or ice crystals, which are what are seen as clouds or fog.

Even though the ocean and frozen lakes are both connected to water, condensation is not a direct result of either of these. As opposed to condensation, water vapour rising from plants is a result of transpiration.

Thus, the correct option is C.

Write a short paragraph about electrical current using the terms conductor and insulator.

Answers

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. ... Most atoms hold on to their electrons tightly and are insulators.


I believe that’s what your talking about if not I’m so sorry

Answer:

Bet

Explanation:

In a conductor, electric current can flow freely, in an insulator it cannot. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. ... Most atoms hold on to their electrons tightly and are insulators.
