Time domain
The relations between voltage and current for the classic dipoles (resistor, inductor, capacitor), in the time domain, are written:
, where
(t) is the current flowing through the resistor and
the voltage drop across the resistor.
, where
(t) is the current flowing throught the inductor and
the voltage drop across the inductor,

, where
(t) is the current flowing through the capacitor and
(t) the voltage drop across the capacitor.
