Objective: Determine inductive impedance as a function of inductance and frequency

Any change in the current through a coil induces a voltage. If an alternating current flows, an AC voltage will be induced, which is shifted in phase with respect to the current. In mathematical terms, the relationship can be expressed most easily if current, voltage and impedance are regarded as complex values, whereby the real components need to be considered. In this experiment, a frequency generator supplies an alternating voltage with a frequency of up to 2 kHz. A dual-channel oscilloscope is used to record the voltage and current, so that the amplitude and phase of both can be determined. The current through the coil is given by the voltage drop across a resistor with a value which is negligible in comparison to the inductive impedance exhibited by the coil itself.
