What does conduction of different metals mean?
it means the rate transfer of heat through this metal and coductivity is the measure of this abillity
How galvanometer helps in marketing research?
The skin's electrical conductivity changes with emotion. The galvanometer measures electrical conductivity. A polygraph (lie detector) uses this principle to determine the anxiety level involved in a response to a question. The subjects of the research could be monitored for their galvanometric response to different stimuli (products). The researcher could use the data to conclude that one stimulus elicits a stronger emotion than some other stimulus and is, therefore, better.
How is the first Television different from ours?
The first television is very different from the ones we have now because of the depth , picture quality , and color.
What are five properties of metal?
The properties of a metal a) Hard to cut b) Have a mettalic lustre c) High melting point d) Melleable e) Ductile f) Sonorus Some metals are used as the most important substances in industries because of its different properties.eg iron and copper I hope this is what you wanted to know
5 bad conductors of electricity?
-- the starter and the cigarette lighter in a car-- the filament in a light bulb-- the third rail on the commuter-train track-- the heater wire in the toaster-- the AC line cord from the refrigerator-- the 'voice coil' in a loudspeaker-- the coax cable down from the TV antenna or satellite dish-- the ethernet cable from your modem to your laptop-- the waveguide up to the microwave dish-- the plasma column inside a strobe tube or neon sign
What is the significance of electrical conductivity in chemistry?
Electrical conductivity in chemistry is significant because it helps determine the ability of a substance to conduct electricity. This property is crucial in various applications, such as in identifying different types of compounds, understanding chemical reactions, and designing electronic devices.
What is the significance of the conductivity tensor in the field of materials science and how does it influence the electrical properties of materials?
The conductivity tensor is important in materials science because it describes how materials conduct electricity in different directions. It influences the electrical properties of materials by determining how easily electricity can flow through them, which is crucial for designing electronic devices and understanding the behavior of materials in various applications.
How does the gas electrical conductivity vary with different factors?
The electrical conductivity of gas can vary based on factors such as temperature, pressure, and the presence of impurities. Generally, higher temperatures and pressures can increase conductivity, while impurities can either increase or decrease conductivity depending on their nature.
What is the significance of the sigma symbol in the context of electrical conductivity in physics?
The sigma symbol represents electrical conductivity in physics. It is a measure of how well a material can conduct electricity. A higher sigma value indicates better conductivity, while a lower value indicates poorer conductivity. The sigma symbol is important in understanding the flow of electrical current through different materials.
Is silver a semiconductor, or does it have different electrical properties?
Silver is not a semiconductor; it is a metal with different electrical properties. Silver is a good conductor of electricity due to its high conductivity, making it useful in various electrical applications.
Do different materials have the same resistance?
No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
What are the functions of conduction units in the context of electrical conductivity?
Conduction units in electrical conductivity serve to transfer electrical signals or currents between different components in a circuit. They facilitate the flow of electricity by providing a pathway for the movement of electrons. This allows for the transmission of information or power within a system.
What is relative conductivity?
Relative conductivity refers to the ability of a material to conduct electricity compared to a standard material. It is commonly used to compare the conductivity of different materials based on their relative values. Materials with higher relative conductivity values exhibit better electrical conductivity than materials with lower relative conductivity values.
What is the difference between thermal and electric conductivity?
Electrical conductivity is flow of electrons between two different points having different electric potentials. Thermal conductivity is flow of electrons between two different points having different temperatures. Electrical Conductivity in solids, is purely based on number of free electrons (number of free electrons and holes in semiconductors). But thermal conductivity is based on number of free electrons and also phonons. Electrical conductivity in liquids and gases is also depends on number of free electrons but thermal conductivity in liquids and gases is because of molecular collision.
Why do you not use silver for conducting electricity?
For electrical conductivity silver has not much advantage copper is much cheaper. The electrical conductivity advantage for silver is in the ratio 63.0 to 59.6. Silver 18.50 USD/oz Copper 3.8 USD/lb Note the different units for the comparison.
How does the material the wire is made of make a difference?
The material of the wire affects its electrical conductivity, flexibility, strength, and resistance to corrosion. Copper is a common choice for electrical wiring due to its high conductivity and flexibility. Aluminum is also used for overhead power lines due to its lighter weight. Steel wires are more durable and have higher tensile strength, making them suitable for fencing and construction.
What is difference between the conductivity of aluminum and gold?
Gold has higher electrical conductivity compared to aluminum. This means that gold is a better conductor of electricity than aluminum, allowing it to transmit electrical current more efficiently. This is one of the reasons why gold is often used in electrical contacts and connectors in electronic devices.
