What is Ammeter in Physics




A galvanometer having a low resistance in parallel is called as ammeter. It is used to measure current. The low resistance connected in parallel is called shunt.





When current is passed through a Galvanometer, its coil is deflected and pointer attached with the coil moves over a Scale. The range for the measurement of current in a galvanometer is very small. Therefore, a low resistance in parallel is used with a galvanometer. This resistance by passes a great part of the current. Only a small amount of current passes through the galvanometer coil, which is within the range of l the galvanometer. This resistance acts as a shunt. An ammeter is always placed in series with other circuit components through which current is to be measured.


Note: The next link is the middle one. Here, students are taught, except for elementary subjects, physics, chemistry, computer science. In the senior classes there are optional items. After compulsory general education, school graduates enter professional and specialized schools. Only after that the Chinese can enter the university. There are three types of higher education in the PRC. These include courses with specialization, the duration of which is three years, the bachelor’s degree – it will take 5 years to complete the training, the master’s program will have to undergo additional training for 3 years. Recently, as part of the development of international relations, Chinese universities are actively inviting students from abroad and implementing exchange programs. In the United States there is no common tradition of education. Each state has its own system and norms. And the state administration controls the educational processes. Despite this, all programs are similar. Experts argue that this is due to the impact of common factors, the country’s needs, and internal migration of the population.
