Energy Content and Electromagnetic Force

C1.4 ENERGY CONTENTS / FORCE MANIFESTATIONS C 1.4.1 Energy contents The energy stored in a capacitor can be described as …………… C 1.4.2 Force action from electromagnetic fields Parallel current carrying conductors are surrounded by magnetic fields exerting forces on each other. If currents flow in the same direction the ...

Losses (ESR, IMP, DF, Q)

C1.3 LOSSES C 1.3.1 Impedance and ESR A capacitor creates in AC circuits a resistance, the capacitive reactance (Formula C1-3). There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one. Finally the capacitor has resistive losses. Together ...

Capacitance, Dipoles and Dielectric Absorption

C1.1 CAPACITANCE The Capacitance is determined by, among other things, the characteristics of the dielectric material. International standards speak of the Dielectric Constant or permittivity, designated by the symbol ε. C1.1.1 Description A capacitor serves as a reservoir for electric charges. The size of the ”reservoir” is called capacitance and ...
