A capacitor is connected in a circuit with a variable-frequency voltage source. The impedance and phase displacement are determined as a function of frequency and of capacitance. Parallel and series impedances are measured.


  • Intuitive, touch-optimized software that controls all devices simultaneously
  • Simplified implementation: all pre-settings already prepared
  • Easy frequency setting thanks to digital function generator
  • Fast and easy experimenting simply by switching components
  • Impedance will be computed in real-time
  • Further experiments in electricity and electronics can be performed with the equipment


  1. Determination of the impedance of a capacitor as a function of frequency.
  2. Determination of the phase displacement between the terminal voltage and total current as a function of the frequency in the circuit.
  3. Determination of the total impedance of capacitors connected in parallel and in series.
