- Physical meaning
- Electrical characteristics between any two points in a circuit
In general, there are often more than one circuit component, but a complex combination of resistance, inductance, capacitance, and transformer. The combination result of each element of any two points in the circuit in series or parallel, its characteristics can be expressed by electrical impedance Ze . Ze = E / I = Re + JXe . In the formula, the symbol e in the lower corner represents the electrical quantity. Generally, Ze is a complex number. In fact, Re is the resistance, and Xe is the imaginary part.
