Since the SI unit for a capacitor is farad, an equation is used to convert from the capacitance in farad to equivalent reactive power in KVAR. In the equation below, C is the capacitance in microfarads, V is the voltage in volts, and f is the frequency in hertz KVAR=C∗2Π∗f...
Power Formula 1– Electrical power equation:PowerP=I×V=R×I2=V2⁄R where powerPis in watts, voltageVis in volts and currentIis in amperes (DC). If there is AC, look also at the power factorPF= cosφandφ= power factor angle ...
When solving the equation Ecos ωt=Rdqdt+qC we assumed that q=Imωsin (ωt+ϕ) and showed that Im=EZtanϕ=1ωRCandZ=R2+(1ωC)2 (a) Show that had we assumed that q=Imωsin (ωt−ϕ) we would have achieved an identical result except that ...

Some principle voltage-operated structures with a contactless moving electrode are shown, together with relations useful for feasibility evaluation. Application to oscillating-mass systems based on electrical levitation is considered. They allow the force balance and the current generation to be performed ...
where the voltage and current are given by equations 4.37 and 4.38, respectively, and the asterisk denotes a complex conjugate. On a lossless line, since there is no dissipation, the average power is independent of position z. Therefore, the voltage and current in equation 4.57 can be calculat...
• Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. • Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this ...
, 1992, and references therein), the extent to which these effects can be described by purely coulombic calculations (e.g., via the PB equation) is presently unclear. Noncoulombic site-binding or Hofmeister preferential interactions of anions with the protein may be involved. These effects may ...
