Does capacitance exist between two thin current-carrying conductors Explain?
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
What impact does osmosis and diffusion have on life?
If osmosis and diffusion didn't exist then cells In things would be dry and shrink
Show experiment to prove current flow opposite to direction of electron flow?
In metal conductors, an electric current is a drift of free electrons from a negative to positive. Period! 'Conventional' current (positive to negative) is, as its name indicates, nothing more than a convention -based on an assumption made before the true nature of electricity was determined. In other words, it doesn't exist! So no experiment can 'prove' that conventional current exists because it doesn't exist! The direction of conventional current was based on the assumption, by the likes of Benjamin Frankin, who assumed that an electric current was some sort of fluid which, of course, would flow from a high (positive) pressure to a low (negative) pressure. The discovery of the structure of the atom confirmed that a current (a flow of electrons, in metal conductors) flowed from negative to positive. Think of it this way. When you look at a led display in a waiting room ('take a ticket'), are the illuminated leds moving to the right, or are the unilluminated leds moving to the left? Think of the illuminated leds as electron flow, and the unilluminated leds as conventional flow.
What exist mostly as a gas and is brittle and not good conductors?
carbon (exists as CO2)
Why can't an electric current exist if the circuit is broken?
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
What is the structure of mines in West Virginia?
Slope, Drift and Shaft mines all exist in West Virginia.
What coastal defenses exist in Bridlington?
Bridlington's defences consist of groynes on the beach, which lessen the effects of longshore drift.
When did the continent Gondwana exist?
The continent Gondwana existed primarily during the Paleozoic and Mesozoic eras, between about 600 to 180 million years ago. It gradually broke apart due to the process of continental drift, leading to the formation of the current continents we have today.
Similar rock structures exist in the Appalachian Mountains and in Greenland and western Europe?
True. This is all because of continental drift
The property of an electrical device that permits storage of electrically separated charges when potential differences exist between the conductors is called what?
Capacitance.
Why does the Pangaea supercontinent no longer exist?
The Pangaea super-continent no longer exists because it has broken up into the continents that exist today, as a result of continental drift caused by convection currents in the earth's mantle.
What is a single negative electric charge that contributes virtually no mass to an atom?
electron ,Believe it is called a FREE electron. Because it is not internally bound to the nucleolus of the atom. in a conductive material , like copper, they are free to drift from one atom to another. if it was not for free electron's ,electricty(current) could not exist.
