Other factors of influencing er effect such as size and shape of particle, volume fraction, electricfieldstrength, shear rate, temperature are discussed.
Based on the relationship of electricfieldstrength and electric potential, the capacity of non-parallel plate capacitor is derived from solving differential equations.
