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.
Figure 10.2: The galvanometer with the solenoid coil, magnet and compass. â¢ Mapping a Magnetic ï¬eld: Put the bar magnet on a piece of paper and trace it. with a pencil. Place the compass on the paper near the magnet and draw an arrow. that points in the same direction as the compass needle points at that position.
