Question

1. Explain an activity to Transform poor
electric conductor into a good Electric
conductor?​

Answer 1

Explanation:

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.



Overhead conductors carry electric power from generating stations to customers.

In order for current to flow, it is not necessary for one charged particle to travel from the machine producing the current to that consuming it. Instead, the charged particle simply needs to nudge its neighbor a finite amount who will nudge its neighbor and on and on until a particle is nudged into the consumer, thus powering the machine. Essentially what is occurring is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorously. This momentum transfer model makes metal an ideal choice for a conductor; metals, characteristically, possess a delocalized sea of electronswhich gives the electrons enough mobility to collide and thus effect a momentum transfer.

As discussed above, electrons are the primary mover in metals; however, other devices such as the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell rely on positive charge carriers. Insulators are non-conducting materials with few mobile charges that support only insignificant electric currents.

Answer 2

Hey mate........

Explanation:

Properties/behavior of any material in the universe are solely dependent on the atoms & its constituent particles.

Insulators are consisting of atoms having very few free electrons & conductors are made of of atoms having large number of free electrons.

Ideally speaking, we can convert any material into other.

For example, if we reduce temperature of materials such as Copper below minus 234.5 degree centigrade then it starts operating as superconductor (resistance becomes zero).

Let’s take one more example.

Consider PVC/rubber as an insulator (which is generally used to insulate conductors in cable/wires). Now if this cable carrying current comes across harsh environmental conditions such as increase in temperature, moisture, etc. then it may lead to leakage of current through the insulator. But it will never act as conductor.

So one cannot convert an insulator into conductor or vice-versa. Constituent particles of material are cause of their nature/behavior.

If one is able to change the atomic structure, then one can convert any material into other.

Hope it helps........
