It generally measures the impedance of current through the body. It measures the opposition of the tissues in the body against the current discharges. This allows the calculation of various current frequency and their relative measurements, and are able to estimate the total body water weight. This data along with the individuals age, weight, sex and such and used in pre-derived equations to calculate fat % and such. The test's accuracy on the other hand may be questioned.

Which tests are most important in analyzing your body composition?
There are about four tests that are important in analyzing the body composition. These tests are the Dexa Scan, Hydrostatic weighing, and Bioelectric Impedance.
What is dynamic impedance?
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
What has the author Duncan E Woods written?

What is Miller's Theorem?
Milller's Theorem is used to simplify a circuit for circuit analysis. Instead of one impedance, which connectes two non-grounded nodes, Miller's Theorem allows this impedance to be broken down into two parallel impedances. One impedance can be seen as Z/(1-A) and the other impedance can be simplified to Z/(1-(1/A)). In this case, Z was the value of the original impedance, and A is the gain of the amplifier being analyzed.
What does bioelectrical impedance analysis do?
Bioelectrical impedance measures the total amount of water in the body, using a special instrument that calculates the different degrees of resistance to a mild electrical current in different types of body tissue.
Will 8 ohm speakers work with 816 ohms of impedance?
yes but will barely hear anything. If you have 816 Ohms of impedance then your speaker is probably bad.
Why capacitor not work with DC supply?
in a dc frequency=0 impedance is xc=1/2*pi*f*c so impedance infinite
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
Why is impedance matching used in electronics?
Impedance matching is used in electronics to get an electronic device with an input and output source to work. Impedance matching will give the electronic it's maximum transfer of voltage. An example of this are FM radio receivers.
What is the impedance of a single phase inductive circuit having a voltage of 240volts and a current flow of 10amps?
Work it out for yourself. The equation is: Z = E/I, where Z is the impedance, E is the supply voltage, and I is the load current.
Why do not you use impedance in DC circuit?
Actually, its a matter of terminology... Impedance can be used in a DC circuit. We just call it resistance, however, transient analysis would imply a different notation. To be clear, impedance is normally used in AC circuits, and it is the electrical opposition to AC, taking into account not only voltage, but phase angle. In a DC circuit, impedance and resistance are the same thing, simply with a phase angle of zero.
