electroscope वाक्य

उदाहरण वाक्य

1. When the electrical contact to earth is broken, e . g . by lifting the finger, the extra charge that has just flowed into the electroscope cannot escape, and the instrument retains a net charge.
2. Cavallo was often cited in the literature of his time as inventor of Cavallo's multiplier, a device he used for the amplification of small electric charges, making them observable and measurable in an electroscope.
3. In other words, the electroscope's rod ( a single probe ) does not remove electrostatic energy from a charged object, because the rod is not in contact with two points along a voltage gradient.
4. "' 1774 "': Georges-Louis LeSage builds an electrostatic telegraph system with 26 insulated wires conducting Leyden-jar charges to pith-ball electroscopes, each corresponding to a letter of the alphabet.
5. Trans ., 1787 ), as a device similar to the electrophorus, but that could amplify a small charge by means of repeated manual operations with three insulated plates, in order to make it observable in an electroscope.
6. -- Electroscope Inc . ( ESCP US ) was rated " buy " in new coverage by analyst Sandra Hollenhorst at John G . Kinnard & Co . The 18 month price target is $ 21 per share.
7. Figuier was probably misled by the article " The Electroscope " published in " The New York Sun " of 29 March 1877, as well as a published letter in the journal " Nature " in April 1878.
8. Induction causes a separation of the charges inside the electroscope's metal rod, so that the top terminal gains a net charge of opposite polarity to that of the object, while the gold leaves gain a charge of the same polarity.
9. However, if you'd rather continue to believe that laboratory electroscopes can produce energy from nothing, you won't be interested in the results . 199.232.231.114 03 : 28, 26 Jun 2005 ( UTC )"
10. But if an electrical contact is now briefly made between the electroscope terminal and ground, for example by touching the terminal with a finger, this causes charge to flow from ground to the terminal, attracted by the charge on the object close to the terminal.
