Capacitor in the AC circuit with Cobra3 and the FG module

Product No: P2440515

Principle

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.

Tasks

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

What you can learn about
