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.
You add a large series resistor to make it into a voltmeter. You add a small shunt (parallel) resistor to make it into an ammeter. Example. If the galvo full scale is 20mV and 20uA, ie, 1k resistance. To make the galvo into a 1 amp FS ammeter, a shunt resistor of: Req = 20mV/1amp = 20m. galvanometer is a type of ammeter: an instrument for detecting and measuring electric current. It is an analog electromechanical transducer that produces a rotary deflection of some type of pointer in response to electric current flowing through its coil.
