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.
AC Amp Meter. An AC amp meter is used in two ways. One AC amp meter uses a system similar to a DC amp meter. The only difference is that an AC amp meter uses a bridge diode instead of a regular shunt as a resistor to measure current.The bridge diode changes negative into positive current to facilitate calibration and measurement.This is called the direct AC amp meter.he voltage drives a needle to help read the measurements of the current. This is called an indirect amp meter. Some AC amp meters are moving iron type amp meters. The magnetic field is attracted by a piece of metal mounted at one end of a needle. This type of moving iron amp meter can work also with DC.
