The symbol of the impedance is Z. What is the function of pole pieces installed in the generator housing? (T/F). The electrons in a wire carrying direct current move slowly, but eventually they travel from one end of the wire to the other because they keep plodding along in the same direction. Reactance only occurs in AC circuits (alternating current). A capacitor effectively DC and AC current through a circuit. As a result, only the wires original resistance is used. The voltage in AC circuits also periodically reverses because the current changes direction. We can name R as resistance, C as capacitance, and Las inductance.
