Question

A tester is used to check the conduction of electricity through two liquids, labeled and. It is found that the bulb of the tester glows brightly for liquid while it glows very dimly for liquid. You would conclude that:
(A) The liquid is a better conductor than liquid.
(B) The liquid is a better conductor than liquid.
(C) Both liquids are equally conducting.
(D) Conducting properties of liquid cannot be compared in this manner.

Answer 1

Conductivity is the measure of the benefit at which an electrical charge or heat will meet up with material. A conductor could be a material that provides little or no resistance to the flow of an electrical current or thermal energy.

Complete step-by-step answer:
There are different types of conductivity present which are solid, liquid, gases and another one is plasma. One by one we will see this.
The conductivity of Solids:
Metals — contain several free electrons (good conductors). Glass, fused quartz, rubber — smart dielectric few free electrons Insulators have a High resistance (Structural resistance to electrons flow).
Semiconductor — a cloth with resistance between conductor and an insulator. The conductivity of Liquids pure liquids doesn’t conduct. Liquid with dissolved ions conduct.
The conductivity of Gases conducts when ionized (charged) once exposed to high energy radiation. Or field of force. Or with a collision with high-speed particles. Charge during a gas is transferred by ions and electrons.
The amount of current flowing through a conducting solution depends on the conductivity of the solution. A lot of the conductivity, more current passes through the solution and vice-versa.

Hence, the conductivity of liquid A is over the conductivity of liquid B.

Notes A good conductor could be a body that permits massive electrical phenomena through it. A bad conductor could be a body that permits little amounts of current through it. Conductivity is the reciprocal of impedance.
Factors on that conductivity depend on:
Length of the conductor, space of conductor, Temperature of the conductor and the Material of the conductor.
