Either an ammeter or a galvanometer is.
A multimeter is a common instrument used to measure electrical current. It can measure current, voltage, and resistance in electrical circuits.
Frequency counter
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
Hydrometer
The Ammeter XD
A low resistance ohmmeter is used
A multimeter is commonly used to measure electrical pressure in a circuit. It can measure voltage, current, and resistance, providing a comprehensive view of the electrical characteristics in the circuit.
The medical term is electroencephalograph (EEG), which is a device used to measure the electrical activity of the brain.
an oscilloscope
It measures the current.
Rheostat is the name of an instrument used to vary electrical resistance.
The electrodynamometer was invented by Werner von Siemens in 1867. It is a type of instrument used to measure electrical power.
