A galvanometer is used to measure small currents.
A pulse oximeter measures the body's oxygen saturation with a small clip.
A galvanometer is called a sensitive instrument because it is capable of detecting even small currents passing through it. Its design allows for precise measurement of small electrical currents, making it highly sensitive to changes in current flow.
Electrodynamometer: An instrument that measures large amount of electric current by indicating the strength of repulsion or attraction between the magnetic fields of two sets of coils, one fixed and one movable. whereas, Galvanometer: An instrument for detecting and measuring small electric currents.
This instrument is a balance.
An instrument that measures heat and cold is called a thermometer.
A microammeter is a measuring instrument used to detect small electric currents, typically in the range of 1 to 1000 microamperes (µA). It is designed to measure low-level currents with high accuracy.
An alternative name for the unit Volt Squared Ohm (VOM) is a multimeter or a multi-tester. This is an instrument that measures voltage, currents, resistance.
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
An ampere meter
A measuring cyling ( you fill it up with water then you put the stone in and the change is the volume)
An anemometer is the instrument that measures wind direction using a wind vane.
A moving coil galvanometer is sensitive and accurately measures small currents due to the rotation of a coil in a magnetic field, producing a deflection proportional to the current. It is preferred for measuring small currents because of its high sensitivity and low electrical resistance.
