• Small currents in the milliampere or microampere range can be measured using milliammeters and microammeters. • A tool that monitors the current flowing across a circuit is an ammeter. • The phrase refers to the ampere unit used to measure electric currents ( A ). • Typically, the circuit that will be used to measure the current and the ammeter are wired in series. • An ammeter typically has a low resistance, which prevents it from significantly lowering the voltage in the circuit it is monitoring. • Every ammeter has a range selection, hence it is impossible to generalize the least count. • Let the range of a certain microammeter is between 0 and 600 mA, and the subdivision in each main scale is 60. • The smallest value that can be measured by a measuring instrument is called its least count. • Least count = smallest count on main scale Number of divion on main scale • The least count of microammeter is 600 60 = 10 mA

Micrometers can be classified into mechanical dan digital models based on their working principle. These different working principles also affect the way these micrometers display the measurement reading. The mechanical model further varies based on how it shows the reading: dial, mechanical counter, and conventional micrometer. Advertisements If you are going to buy a new micrometer, perhaps this post can be helpful for you. We will present the advantages and disadvantages of each model in several points. Mechanical Micrometer Mechanical micrometers mean no electronic circuit that empowers these measuring tools. Therefore, it can be a dial micrometer, mechanical counter micrometer, vernier scale micrometer, and the general mechanical micrometer (without vernier scale). However, the most used are the general and vernier scale micrometers. The general model micrometer applies Advertisements Some models come with an additional Advantages: • Affordable. It has a relatively lower price compared to the digital micrometers. • No battery. You could put it and use it anytime you want without worrying whether the battery power is enough or not. There will be no suddenly unable to use it when you are really needing it (during the job) like the digital mic does when it runs out of battery. • Last for a longer time. You don’t need to worry that the electronic circuit breaks apart and the battery leaks. • Can be used in a harsh environment. No need to worry to use it in an oily or magn...
