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.
Many older model and high performance vehicles have an ammeter (a gauge which display the current draw on your battery) and this can tell the operator that their vehicle isn't charging the battery. The most obvious signs will be the car's electrical system malfunctioning (radio sounding garbled,lights dimming,etc).
