Coil in the AC circuit with Cobra3 and the FG module

Product No: P2440411

Principle

The coil is connected in a circuit with a voltage source of variable frequency. The impedance and phase displacements are determined as functions of frequency. Parallel and series impedances are measured.

Tasks

Determination of the impedance of a coil as a function of frequency.
Determination of the inductance of the coil.
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 coils connected in parallel and in series.

What you can learn about

Inductance
Kirchhoff´s laws
Maxwell´s equations
a.c. impedance
phase displacement
