MEASURING IMPEDANCE
In order to measure the impedance of an unknown circuit element, you connect it in series with a known resistance of 37Ω and an AC power source with a voltage amplitude of 2V and a frequency of 234Hz. When you connect an oscilloscope across the known resistor, you measure a voltage amplitude of 0.86V that is 1.84ms ahead of the supplied voltage.
