how can we get any desired value of capacitance
Answers
Answer:
The capacitance of a capacitor is the ability of a capacitor to store an electric charge per unit of voltage across its plates of a capacitor. Capacitance is found by dividing electric charge with voltage by the formula C=Q/V.
Capacitance (symbol C) is measured in the basic unit of the FARAD (symbol F). One Farad is the amount of capacitance that can store 1 Coulomb (6.24 x 1018 electrons) when it is charged to a voltage of 1 volt.
Answer:
The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used. The dielectric constant, εo also known as the “permittivity of free space” has the value of the constant 8.84 x 10-12 Farads per metre.
