What is fundamental unit of electric charge?
Electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb. …
What is called fundamental charge?
The elementary charge, usually denoted by e or sometimes q e is the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e . This elementary charge is a fundamental physical constant.
What is the basic unit of current?
The ampere (/ˈæmpɛər/, US: /ˈæmpɪər/; symbol: A), often shortened to “amp”, is the base unit of electric current in the International System of Units (SI). It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electromagnetism.
What is the basic unit of electricity *?

What is the smallest unit of charge called?
The smallest unit of charge is −1.6×10−19 C, which is the charge in coulombs of a single electron. Robert Millikan was able to measure the charge on small droplets of oil by suspending them between a pair of electrically charged plates.
Is Franklin a smallest unit of charge?
Franklin is the smallest unit of charge and it is the physical unit of electric charge which is used in cgs system while faraday is the largest unit of charge.
What is unit vector used for?
(pronounced “v-hat”). The term direction vector is used to describe a unit vector being used to represent spatial direction, and such quantities are commonly denoted as d; 2D spatial directions represented this way are numerically equivalent to points on the unit circle.
