BIA for a simple RC circuit
During the first part of the laboratory, experimentation with a series RC circuit is undertaken to confirm the frequency dependence of phase angle and impedance. This also serves as an introduction to the functionality of the educational BIA device. Students analyze the potentials across circuit components when a resistor and capacitor are connected in series to the educational BIA device (Fig. 5). At low frequencies (5 kHz) students measure the voltage ratios and phase differences from the dc outputs of the educational BIA device [Fig. 5(b)] as described above by Vphase and Vmag.
