Is zinc an good or bad conductor of electricity?
zinc is a good conductor of electricity
What are some ways a material's electrical resistance is used to accomplish a certain job?
A good example of electrical resistance is the heating element on a stove top it is a very poor conductor (high electrical resistance) because it is a poor conductor the electrical energy is converted to heat. Glass is one of the best insulators because its electrical resistance is so high it is a non conductor this lets us use it on high power lines to keep the electricity from coming in contact with the ground.
What is skin effect?
<center> # 2 If the conductor is composed of one or more concentric circular elements, then the center portion of the conductor will be enveloped by a greater magnetic flux than those on the outside. Consequently the self induced back-emf will be greater towards the center of the conductor, thus causing the current density to be less at the center than the conductor surface. This extra concentration at the surface is known as skin effect, and results in an increase in the effective resistance of the conductor.
What are some of physical media that ethernet can run over?
d
Advantage and disadvantage of corona of transmission line?
advantages:due to corona formation the sir surrounding the conductor becomes the conducting and hence virtual dimeter of the conductor is increased.
Does liquid conduct electricity well?
It depends on the liquid. Oil would not be a good conductor of electricity. Water is a good conductor, though distilled water is not. Any liquid metal or ionic compound would be a good conductor.
What is a good conductor of heat in liquid?
mercury
What solids are good conductors?
All metals are solids and good conductors apart from Mercury which is a liquid but is a good conductor.
Why should liquid used in a thermometer be a good conductor of heat?
The liquid in a thermometer should be a good conductor of heat so it can quickly and accurately reflect changes in temperature. Good conductivity ensures that the liquid expands or contracts rapidly with changes in temperature, allowing for precise temperature readings.
Does the type of container hot liqid is placed in effect how hot it stays?
the temperature of a liquid in a container depends upon whether it is a good or a bad conductor of heat. a good conductor takes up most of the heat of the liquid (process of thermal equilibrium) while bad conductor does not absorb heat very quickly
Is sodium chloride liquid the best conductor of electricity?
Liquid sodium chloride is a conductor but not the best.
Is Ink is conductor of heat?
No, ink is not a good conductor of heat. Inks are typically made from pigments or dyes mixed in a liquid base that does not conduct heat well.
What element that is a good conductor of electricity It also forms a chloride in the form XCl2 and an oxide in form of XO.The element is a liquid at room temperature.What is the identity?
Mercury is the only element that is both liquid at room temperature and a good conductor of electricity. Mercury also has the other properties specified.
Why is liquid mercury a good electrical conductor?
Liquid mercury is a good electrical conductor due to its high electron mobility and low resistivity. The electrons in the liquid metal are able to move freely, allowing for the easy flow of electric current. Additionally, mercury has a high density, which helps to facilitate electron conduction.
Why is foam a good conductor?
Foam is not a good conductor; in fact, it is an insulator. Foam is made up of many small pockets of gas trapped within a solid or liquid material, which greatly hinders the flow of electric charge, making it a poor conductor of electricity.
Is liquid an electricity conductor?
some
Why water is a good conductor of heat?
Water is a good conductor of heat because it is a liquid thus convection currents can flow as well as transferring heat by conduction through the water molecules.
