Question

what do you mean by columb explain​

Answer 1

Answer:

The coulomb (symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere in one second:

{\displaystyle 1~{\text{C}}=1~{\text{A}}\times 1~{\text{s}}} {\displaystyle 1~{\text{C}}=1~{\text{A}}\times 1~{\text{s}}}

Thus, it is also the amount of excess charge on a capacitor of one farad charged to a potential difference of one volt:

{\displaystyle 1~{\text{C}}=1~{\text{F}}\times 1~{\text{V}}} {\displaystyle 1~{\text{C}}=1~{\text{F}}\times 1~{\text{V}}}

The coulomb is equivalent to the charge of approximately 6.242×1018 (1.036×10−5 mol) protons, and −1 C is equivalent to the same amount of electrons.

A new definition, in terms of the elementary charge, took effect on 20 May 2019.[2] The new definition defines the elementary charge (the charge of the proton) as exactly 1.602176634×10−19 coulombs.
