Principle
Series circuits containing self-inductances or capacitances and ohmic resistances are investigated as a function of frequency. Measuring the electrical magnitudes with a work or power measurement instrument, real power or apparent power can be displayed directly.
Benefits
- Quick set-up
- Investigate the influence of electrical components in an AC circuit.
- Directly measure the real or apparent power
Tasks
