Phase Relationships in AC Circuits
Phase When capacitors or inductors are involved in an AC circuit, the current and voltage do not peak at the same time. The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference. The phase difference is = 90 degrees.= 90 degrees.
Inductance vs. Impedance: What''s the Difference?

The Fundamentals of Capacitors in AC Circuits
When two capacitors are placed in series, the effect is as if the distance between the outside plates were increased and the capacity is therefore decreased. On an alternating current supply, this effectively increases the opposition to a current flow in a similar fashion to that of resistors placed in series:

How Parasitic Capacitance and Inductance Affect Your Signals
The analog signal from one trace/component can induce a low level oscillation in another trace/component when the parasitic inductance is as low as 1 nH. Parasitic capacitance also leads to crosstalk, and even low levels of parasitic capacitance can affect the gain of amplifier circuits. Reducing Parasitic Capacitance and Inductance
AC Inductor Circuits | Reactance and Impedance—Inductive
This results in a voltage wave that is 90° out of phase with the current wave. Looking at the graph, the voltage wave seems to have a "head start" on the current wave; the voltage "leads" the current and the current "lags" behind the voltage. Current lags voltage by 90° in a pure inductive circuit.
5.3: Inductance
That induces an emf across the solenoid, which will in turn have an effect on the current through it! This process is known as self-inductance. We actually define self-inductance in the same way that we defined mutual inductance – the ratio of the total flux through the (N) coils to the current that supplies the magnetic field.

decoupling capacitor
As a matter of practical procedure, the way lead frame inductance is estimated is to measure the S-parameters of a packaged calibration die, de-embed the S-parameters of the lead, and convert that to an equivalent best fit added inductance that gives similar asymptotic results when used in a simulator at low enough frequencies.
