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.
The ampere, often abbreviated to amp or A. It measures electrical current which is denoted in Ohm's Law as I. The unit or instrument used to measure electric is called AMMETER. More detail. The unit is named after the French physicist AndrÃ© Marie AmpÃ¨re. <><><>. A current of 1A is equal to 1 coulomb of charge passing a point in 1 second.
