n: (C) the ratio of an impressed electrical charge on a conductor to the change in electrical potential;measured in farads. See capacitor.

n: a device used in most net-oil computers that senses the different dielectric constants of oil and water in a water-oil emulsion. See dielectric constant.

Measures the fluids capacitance – uses the wellbore fluid as the fluid between plates of a capacitor.

n: (F) the unit of electrical capacitance.

n: (Z) 1. the total resistance a circuit has to the flow of electricity. 2. the sum of resistance and reactance in an AC circuit. Measured in ohms.

total opposition (resistance, capacitance and inductance),expressed in Ohms, to the flow of current.
