Impedance, commonly represented by symbol Z, measured in ohms (Ω), influence a circuit's opposition to the current flow. It consists by two parts: resistance and reactance, expressed by the formula Z=R+jX. Here, R is the resistance, which always impedes the current flow; X is the reactance, caused by inductance (inductive reactance) and capacitance (capacitive reactance), and it...
