Resistance, phase shift and power in AC circuits with digital function generator

Project Description

PrincipleSeries 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
