In one measurement of the body's bioelectric impedance, values of Z=5. 53 ‚úñ 10¬≤ Œ± and delta=-8. 15° are obtained for the total impedance and the phase angle, respectively. What does Z represent in this measurement?
1) The total impedance of the body
2) The phase angle of the body
3) The voltage of the body
4) The resistance of the body.
