The actual DC current flowing through a capacitor consists of three elements: charging current, absorption current, and leakage current. The "pure" leakage current is not only a current that is passing through the bulk of the dielectric layer, but also bypassing between electrodes without going through the dielectric.
As mentioned above, the actual DC current flowing through a capacitor consists of three elements: charging current, absorption current, and leakage current. The role and characteristics of each element are summarized in Table 2. *16 The three components are discussed in next section.
Series connected capacitors have a common current flowing through them. Capacitive reactance, X C is the opposition to current flow in AC circuits. In AC capacitive circuits the voltage “lags” the current by 90 o. 1.
That is, when voltage is applied to the capacitor, a charging current flows instantaneously, accumulating charge on the electrodes. When the charge to the electrode ends and the charging current decays, an absorption current flows and dielectric polarization begins. When dielectric polarization ends, a leakage current appears.
Figure 5.1.1 Basic configuration of a capacitor. In the uncharged state, the charge on either one of the conductors in the capacitor is zero. During the charging process, a charge Q is moved from one conductor to the other one, giving one conductor a charge + Q , and the other one a charge − Q .
