Frequency domain
Under the hypothesis that the current and voltage are time dependant following a sine law, the following relations can be written using the complex notation.
For the resistor
, where
is the voltage drop across the resistor and i the current flowing through it,For the inductance
, where
is the voltage drop across the inductor and i the current flowing through it,For the capacitor
, or,
, where
is the voltage drop across the capacitance, and
the current flowing through it.
