Therefore, one gets net bone loss, and decreased opacity (increased lucency) of the bone. Decreased Opacity (Lucency) Lucency comes in several flavors. Depending on the exact morphology and distribution of the lucency, our differential diagnosis may vary widely.oth osteoclasts (removers of bone) and osteoblasts (formers of bone) participate in this reaction. In normal bone, the clasts and blasts are more or less in equilibrium, and new bone is formed at the same rate that old bone is reabsorbed.
An ampere, or amp (A or I, for current), is the amount of current in a circuit, while voltage (V) is the strength of the current as it flows through the circuit, and watts (W) are the total electrical power released by circuit per second. One common analogy used to illustrate these terms is that of a garden hose.
Ammeters. Ammeters are tools used to measure the current in a circuit. The ammeter is connected in series with the circuit, so that the current to be measured flows directly through the ammeter.The circuit must be broken to correctly insert an ammeter.nswer: (4) shows an ammeter in series and a voltmeter in parallel with the resistor. Question: Compared to the resistance of the circuit being measured, the internal resistance of a voltmeter is designed to be very high so that the meter will draw.
