Question

What is the least count of a Microammeter?

Answer 1

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