In one measurement of the body's bioelectric impedance, values of Z = 4.73 x 102 and = -6.00° are obtained for the total impedance and the phase angle, respectively. These values assume that the body's resistance R is in series with its capacitance C and that there is no inductance L. Determine the body's (a) resistance and (b) capacitive reactance.
When an inductor with L = 10 mH is attached to an AC voltage source, the inductive reactance is 7900 Ω. What is the capacitive reactance of a capacitor with C = 430 pF when attached to the same voltage source?
