växelströmsanalyser
Växelströmsanalyser, or AC analysis, is a method used in electrical engineering to study the behavior of circuits when subjected to alternating current (AC) signals. Unlike DC analysis, which deals with constant voltage and current, AC analysis considers signals that vary sinusoidally over time. This variation introduces frequency-dependent behavior in circuit components like capacitors and inductors, which become reactances.
The core of AC analysis involves using complex numbers to represent AC voltages, currents, and impedances. Impedance
Key objectives of AC analysis include determining the magnitude and phase of voltages and currents at different
