What is Ammeter, Construction, Working, Types & Applications
Hello, friends, I hope all of you are having fun in your life. In today''s tutorial, we will explain what is ammeter. in 1820 Hans Christian oersted who belonged to Denmark discovered the relationship among current, magnetic field and physical forces (gravitation, electromagnetism, weak interaction, and strong interaction). ...
Ammeter
In this ammeter configuration each shunt resistor, R S of the multirange ammeter is connected in parallel (shunted) with the meter as before to give the desired ampere range. So if we assume our 100uA FSD meter from above is required to measure the following current ranges of 1mA, 10mA, 100mA, and 1A, then the required shunt resistors are …
How to Tell the Positive & Negative Side of a Car Battery?
One of the quickest visual checks for determining battery polarity requires locating the main positive and negative terminals connected to the metal posts extending from your battery''s top. The positive terminal is almost always physically larger in size than the neighboring negative terminal.
