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.
An ammeter is an instrument used for measuring electric current in units of amperes. An ammeter must be connected in series with the path of the current being measured. Setting the ammeter up in parallel will create a short circuit, and will not measure the current correctly.n the image below, each ammeter will also measure the total current of the circuit. Now that we know how to measure the total current through the circuit, let's look at measuring the current travelling through individual elements. Current travels through series and parallel elements differently.
