The spleen (from Greek ÏÏÎ»Î®Î½âsplá¸n) is an organ found in virtually all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (also referred to as erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, and also recycles iron.
Amperage is a term often used by electricians, and means electrical current, measured in amperes, or amps. The ampere is the SI unit for electrical current, or the amount of electrical charge that flows through a conductor in a given time.One ampere is a charge of one coulomb â about 6.241 X 10 18 electrons â per second flowing past a given point. current of one amp at one volt uses one watt of power. The power used by a device is simply amps multiplied by volts, so an appliance rated at ten amps plugged in to a 110-volt supply will use 1,110 watts.
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.
