Capacitance formula with unit and examples

“Capacitance is the ability to store an electric  charge per unit of voltage across its plates of a capacitor .”It is denoted by C.That is capacitance is a measure of a capacitor’s ability to store charge.The more charge per unit of voltage that a capacitor can store,the greater its capacitance. Formula Its formula is given as: C=Q/V Where C is capacitance,Q is ...

coulomb’s law of electrostatics in vector form with examples

Coulomb’s law definition “Coulomb’s law states that  force of attraction or repulsion between two electric charges is directly proportional to their magnitudes and inversely proportional  to the square of distance between them”.It is mathematically explained as: Charles Agustin Coulomb (1736-1806) measured electrical attractions and repulsions  quantitatively and deduced the law that governs them.His apparatus,shown in fig. This figure resembles the ...
