In the posts on inductance and capacitance, we have learned that both conditions are reactive and can provide opposition to
Impedance in RLC Circuits
Impedance in an R-C-L series circuit is equal to the phasor sum of resistance, inductive reactance, and capacitive reactance (Figure
Impedance in RC Circuits
In a capacitive circuit, as in an inductive circuit, impedance is the resultant of phasor addition of R and XC.
