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.
Answers. Best Answer: Similar: they both use the connection between electricity and magnetism to produce a torque due to applied electrical current on a mechanical body. Different: Galvanometers have the torque oppose the torque due to a torsional spring, such that the needle is held stationary for measuring current. Motors encourage continuous rotation of the rotor and shaft, which is enhanced with the addition of the commutator for periodic swapping of the direction of current flow.
