Losses Impedance and ESR A capacitor creates in AC circuits a resistance, the capacitive reactance (Formula C1-3). There is also certain inductance in the capacitor. In AC circuits it produces an inductive reactance that tries to neutralize the capacitive one. Finally the capacitor has resistive losses. Together these three elements produce the impedance, Z.
