A microammeter is a very sensitive galvanometer capable of measuring very small electric current intensities, on the order of microamperes, that is, one millionth of an ampere.
I perform several experiments with a small moving coil microammeter. It is a passive measuring instrument, since it does not have transistors or any type of amplifier that would require being powered with electricity.
It simply works with the electricity it measures.
