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 various. electric meters use resistors in series or in parallel with the galvanometer. In order to choose. a resistor for a speci c purpose you need to know the resistance of the galvanometer and the. current for full-scale de. ection. Caution: Before you use the decade box in the circuit, turn all the knobs.
