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.
In order to convert a Galvanometer into voltmeter, a very high resistance known as series resistance is connected in series with the galvanometer. VALUE OF SERIES RESISTANCE www.citycollegiate.com Let resistance of galvanometer = Rg and resistance Rx (high) is connected in series to it. digital meter works by measuring volts so to use it as an ammeter, you connect it in parallel with a low resistance to measure the voltage dropped across the resistor that is relative to the current (ohms law again).
