A circuit always has a battery (cell) but it can also contain other electrical components, such as bulbs, buzzers and motors. When drawing circuit diagrams, rather than drawing detailed components, we ...

This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...
