Measurement is the process of comparing known and unknown quantities The measurement process is divided into physical quantities, measuring instruments and units of measurement basic quantities meter length mass in kilograms time. the second Intensity of Electric Current. amps temperature. Kelvin material quantity. the mall Intensity of illumination. candela

Capacitor It is the ability of a capacitor to store potential energy in the form of an electric field It is equal to the value of the electric charge over the potential difference The unit of capacitance of a capacitor is the farad The capacitance of the parallel plate capacitor depends on me The common space of the two panels spacing Dielectric tolerance The capacitance of the capacitor is represented by the symbol C .
