Classification of Sedimentary Rocks (Part 1). Sedimentary rocks are classified based on their texture and composition. Detrital sediment has a clastic (broken) texture. Chemical and organic sediments have a non-clastic texture, and are classified based solely on their composition.
Galvanometer vs Ammeter. Ammeter and galvanometer are two devices that are used in the field of electronic and electrical measurements. Galvanometer is a very important device that is used to develop other measuring devices. It is also used to measure electrical currents. Ammeter is also a device that is used to measure electrical current.
Three types of ammeters are used on battery chargers: the direct connected D.C. ammeter, the meter mounted shunt type, and the external shunt type. The direct connected D.C. ammeter, as shown in Figure 18-la, which has one or more turns of heavy wire in the meter, or the cable on the outside, indicating by induction.
