Based on Loyd #36. In this experiment, students will measure the voltage across a resistor, an inductor, and a sine-wave generator (all in series) in order to determine the phase angle of the generator current relative to the generator voltage. They will also calculate the values of pure inductor L and pure resistance r for an unknown inductor. This experiment demonstrates the relative phase angle of the voltage across each of the circuit elements. It also shows the students that real inductors consist of both inductance and resistance, and therefore inductors can be represented by a pure inductor L in series with pure resistance r.

One 100mH or 0.1H inductor is required. Only two of the four inventoried inductance decade box models can be used - models 22 and 32. Either one of these two models should be set at each table.
