Description

The experiment P3.6.6.5 measures the current I_rms through a given load and the active power P_W for a fixed AC voltage U_rms. To verify the relationship

the phase shift φ between the voltage and the current is additionally determined using an oscilloscope. This experiment also shows that the active power for a purely inductive or capacitive load is zero, because the phase shift is φ = 90°. The apparent power

is also referred to as reactive power in this case.
