polarisable

If an isolated piece of nerve be taken and two contacts be made on its surface by means of non-polarisable electrodes at A and B, connection being made with a galvanometer, no current will be observed, as both A and B are in the same physico-chemical condition.

Let us take a bar, one half of which is zinc and the other half copper, clamped in the middle, so that a disturbance produced at one end may not reach the other; the two ends are connected to a galvanometer through non-polarisable electrodes.

The current in the galvanometer through the non-polarisable electrode is from left to right.

The stimulated end of tin, say the end A, thus becomes zincoid, i.e. the current through the electrolyte (non-polarisable electrodes with interposed galvanometer) is from A to B, and _through the wire_, from the less stimulated B to the more stimulated A.

The cup may now be filled with water, and connection made with a galvanometer by non-polarisable electrodes.

Moistened threads in connection with the two non-polarisable electrodes are led to the side tubes _t t'_.

Response in the Living and Non-Living Jagadis Chandra Bose 1897

Or instead of connecting A and B by a single strip of cloth _s_, we may connect them by two strips _s s'_, leading to non-polarisable electrodes

Taking a carrot as the vegetable tissue, I found its resistance plus the resistance of the non-polarisable electrode equal to 20,000 ohms.

Connection is made with the non-polarisable electrodes by the side tubes.

These two faces may be put in connection with a galvanometer by means of two non-polarisable electrodes, whose ends dip into the two chambers.
