Therefore, the electrostatic field everywhere inside a conductive object is zero, and the electrostatic potential is constant. The electric field, E {\displaystyle \mathbf {E} } , in units of Newtons per Coulomb or volts per meter, is a vector field that can be defined everywhere, except at the location of point charges (where it diverges to ...
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
National Examination Board is responsible for conducting and managing 12th grade-Higher Secondary exams and 10th grade Secondary Education Examination (SEE) Exams. [3] The jurisdiction of the previous Higher Secondary Education Board (HSEB) was limited to 11th and 12th-grade high school (10+2) only. HSEB was established in 1989 under the Higher ...
Earnshaw's theorem states that a collection of point charges cannot be maintained in a stable stationary equilibrium configuration solely by the electrostatic interaction of the charges. This was first proven by British mathematician Samuel Earnshaw in 1842. It is usually cited in reference to magnetic fields, but was first applied to ...
In classical electrostatics, the electrostatic field is a vector quantity expressed as the gradient of the electrostatic potential, which is a scalar quantity denoted by V or occasionally φ, [1] equal to the electric potential energy of any charged particle at any location (measured in joules) divided by the charge of that particle (measured ...
An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
The SLC (Class 11 and 12) and SEE (Class 10) examinations are normally scheduled from April to June each year. The examinations are conducted by the National Examination Board (NEB), located in Sanothimi, Bhaktapur, Nepal. Until 2016, SLC was the Grade 10 final examination, famously known as the "iron gate" [citation needed]. However, after ...
Nepal Rastra Bank head office located in Baluwatar, Kathmandu. The Nepal Rastra Bank (NRB; Nepali: नेपाल राष्ट्र बैंक) was established on April 26, 1956 A.D. (Nepali Date: Baisakh 14, 2013 B.S.) under the Nepal Rastra Bank Act, 1955, to discharge the central banking responsibilities including guiding the development of the embryonic domestic financial sector.
