What is ammeter sensitivity?
An ammeter is said to be sensitive if it takes minimum current to produce large deflection.
What does micro amp measure?
Microampere, or microamp: A millionth of an Ampere. Ampere is the basic unit for measuring electrical current. Often written as uA, but the u is a plain-text substitute for the Greek letter mu. Synonyms.
What is the difference between Ma and micro ampere?
The answer is 0.001. We assume you are converting between milliampere and microampere. You can view more details on each measurement unit: milliamperes or microamperes The SI base unit for electric current is the ampere. 1 ampere is equal to 1000 milliamperes, or 1000000 microamperes.
What is a very sensitive ammeter called?
A DC ammeter is thus sensitive to which polarity it is connected in; most are marked with a positive terminal, but some have centre-zero mechanisms and can display currents in either direction.
How can you increase the reading on an ammeter?
To increase the range of ammeter, you need to connect a shunt resistance in parallel to the branch where you want to measure the current. The ratio of resistances connected is multiplied by the shown value of ammeter to obtain the original value.
