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.

True.

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.

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.
