At last he notices that there is a slight movement of the galvanometer needle at the moment of making and breaking the circuit.
The galvanometer before which Devin was seated apparently agreed.
The special difficulty was in securing automatic record of the galvanometer deflections.
To indicate the effect, he included a galvanometer in the circuit of the battery and the button.
The current flowed calmly through the battery wire without producing, during its flow, any effect upon the galvanometer.
An instrument which reveals this condition is called a galvanometer.
A galvanometer was readily affected by using the saddle conductors, applied to the anterior and posterior parts of the gymnotus.
We can determine the relative strengths of two currents by the use of a galvanometer.
The other piece is fastened to a bracket from which the galvanometer is suspended.
In this way the galvanometer will not be disturbed when making connections.
An instrument that detects small electric currents and indicates their direction and relative strength. Current flowing through the galvanometer passes through a coil near a magnetized needle on a pivot; the strength of the current in the coil regulates the strength of a magnetic field that displaces the needle. Galvanometers can be used directly as ammeters, and are the core element of many ohmmeters and voltmeters.
