noun
- instruments used to detect and measure small electric currents by observing the deflection of a magnetic needle or coil
Usage: scientific; plural form
Examples
- The laboratory was equipped with several galvanoscopes for measuring electrical activity.
- Early galvanoscopes were essential tools in the development of electrical science.
- The physicist used galvanoscopes to detect the weak currents in the circuit.
- These sensitive galvanoscopes can measure currents as small as microamperes.
- The students learned to read the deflections on the galvanoscopes during their physics experiment.
- Modern digital meters have largely replaced traditional galvanoscopes in most applications.
