What is the electrical impedance of a capacitor
Impedance, like resistance, hinders current flow but includes both size and direction aspects. It consists of resistance (the real part) and reactance (the imaginary part, arising from the circuit''s inductance and capacitance). When looking at admittance vs impedance, admittance is the inverse (i.e. the reciprocal) of impedance.
