What is cisco telepresence conductor? The Cisco TelePresence Conductor simplifies the use of multi-user video conferencing by intelligently allocating meetings, and optimises the utilisation of resources available on multipoint conferencing servers (MCUs).
Are conductors high resistance? Objects made of electrical insulators like rubber tend to have very high resistance and low conductivity, while objects made of electrical conductors like metals tend to have very low resistance and high conductivity. This relationship is quantified by resistivity or conductivity.
Is low resistance a good conductor? The lower the resistance of a material, the better the material acts as a conductor. For example, copper has a lower electrical resistance than aluminum; copper is a better conductor.
Does conductor have resistance? The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

Is all metals are conductors justify your answer?
Answer: Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.
Which conductor has highest resistivity?
The correct answer is option 1 i.e Mercury. The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. Resistivity, commonly symbolized by the letter ρ (rho).
Why graphite is good conductor of electricity class 10?
Graphite is a good conductor of electricity because of the presence of free electrons in its crystal. … This means that the fourth valence electron of each carbon atom is free. These free moving electrons are responsible for the conduction of electricity in a graphite crystal.
Is a good heat conductor a good insulator?
Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators.
Is skin a good conductor of electricity?
By contrast, our skin is a relatively poor conductor of electricity. Meaning, it resists more of an electric current than it actually conducts over a given distance.
Why temp gradient in conductor generate emf?
If there is a temperature gradient in an electrical conductor, the energy (heat) flow is associated with an electron flow along the conductor and an electromotive force (EMF) is then generated in that region. … The voltage is a function of the temperature difference along the conductor length.
What does a streetcar conductor mean?
Job Description for Subway and Streetcar Operators : Operate subway or elevated suburban trains with no separate locomotive, or electric-powered streetcar, to transport passengers. …
What does conductor size 14 3 mean?
A rating of 14/3 refers to the gauge of the wire and how many conductors are in the cable. In this case, the wire gauge is fourteen (lower numbers mean larger wires) and the three indicates that there are three conductor wires in addition to a non-insulated ground wire.
What factor does not affect the resistance of a conductor?
Conductors show less resistance and Insulators show very high resistance. So it depends on the material. It is inversely proportional to the cross-sectional area of the wire.
Which is true about a charged isolated conductor?
Which is true about a charged isolated conductor? The electric potential is the same throughout the interior and decreases as we move outward from the surface. … The work done by us is positive; the potential energy of the system is positive.
Is fruit a conductor of electricity?
Many people may think it’s amazing that a simple piece of produce can conduct electricity. … “Fruits and vegetables conduct electricity in the same way a salt solution will complete an electrical circuit,” Michael Hickner, an associate professor of materials science and engineering at Penn State, told Live Science.
Is wood an example of a thermal conductor?
Wood exhibits a low thermal conductivity (high heat-insulating capacity) compared with materials such as metals, marble, glass, and concrete. Thermal conductivity is highest in the axial direction and increases with density and moisture content; thus, light, dry woods are better insulators.
What three elements are good conductors of electricity?
Copper, silver, aluminum, gold, steel, and brass are common conductors of electricity. The most highly conductive metals are silver, copper, and gold.
Which conductor shaped the sound of the philadelphia orchestra?
Late in the 1929-1930 symphony season, Stokowski started conducting without a baton. His free-hand manner of conducting soon became one of his trademarks. On the musical side, Stokowski nurtured the orchestra and shaped the “Stokowski” sound, or what became known as the “Philadelphia Sound”.
What is 100 cotton poplin fabric?
100% cotton poplin is a fabric made purely from cotton using a poplin weave. Poplin is a plain weave usually made from different thicknesses of warp and weft threads. For a cotton-only fabric, the poplin uses the same thicknesses across both grains and loses the ribbing effect.
Are cotton balls safe for septic tanks?
Wipes and thick, multi-ply toilet paper aren’t the only products you shouldn’t flush if you have a septic tank. … Along with these non-flushable, dental floss, cotton swabs, cotton balls, cigarettes, and anything solid shouldn’t go down the toilet’s drain.
What is cotton chino drill fabric?
Cotton drill is a highly durable pure cotton fabric with a strong twill weave that offers a diagonal strand appearance and an interesting texture. The fabric comes in vibrant colours and various patterns, which gain their strength and durability because of the presence of twill weaves.
How to test if fabric is 100 cotton?
You can test fabric for 100% cotton using the burn test. Take a few fibers and hold them against a flame. 100% cotton will not curl from the heat. It smells like burning paper and leaves grayish ash without signs of melting.
Do they stuff dead bodies with cotton?
Koutandos said a body’s nose and throat are packed with cotton wool to stop fluids from seeping out. Cotton may be used to make the mouth look more natural, if the deceased doesn’t have teeth. … Makeup—but not too much—is applied to lessen the ‘waxy look’ a dead body might have.
Does cotton gauze stretch?
Our natural cotton tends to relax after it’s hung and/or steamed. Natural fibers stretch quite easily when wet so if you find that your item is a bit snug/short/etc, you can typically gain roominess in any direction by wetting or steaming and a simple hang dry.
Why is cotton prices going up?
Increases in consumer prices are the result of shortages and shipping delays caused by COVID-19 shutdowns in the supply chain as well as the impact of severe weather on crops paired with a boom in demand for household goods since the pandemic started.
