obvious example is a motor, whose windings have an inductance. More generally, a device with a current-induced magnetic field that interacts like an inductor will have inductance. 6.2 The Capacitor Circuit symbol There is a relationship between current and voltage for a capacitor, just as there is for a resistor. However, for the
Relationship between capacitance & power output
I designed an experiment to test out how voltage affected the power output of a capacitor to a motor. The motor had a rotating component whose RPM I used as a means of quantifying the power output. That said I''m not 100% certain that it is indeed a linear relationship despite what the trendline might suggest.

Due to the Pythagorean relationship, the total impedance will always be less than the total sum of the resistance and reactance, assuming both are non-zero values. Impedance in a DC Circuit. Given a DC voltage supply, capacitors will act as open circuits, raising the impedance to infinity and blocking current entirely.
AC Capacitance and Capacitive Reactance
So for a pure capacitor, V C "lags" I C by 90 o, or we can say that I C "leads" V C by 90 o. There are many different ways to remember the phase relationship between the voltage and current flowing in a pure AC capacitance circuit, but one very simple and easy to remember way is to use the mnemonic expression called "ICE".
