These pieces are inclosed in a nickelized copper box provided with a screw cap, C. The resistance of both the receiver and transmitter bobbin is 200 ohms.

When complete, the wire was rather larger than No. 3, English gauge, but varied in diameter, some being as large as No. 1, and it averaged 525 lb. of copper per mile and = 1.5 ohms.

I then placed both ends of the wire to earth through 3,000 ohms resistance, and introduced a small auxiliary battery between the chemical paper and earth.

R. The proportions of the resistance of the main line and the artificial resistances which I prefer to employ may be approximately indicated as follows: Assuming the resistance of the main line to be 900 ohms, the resistance, R, and R', should be each about 3,000 ohms.

This is equal to the effect produced by a Grove's cell in a circuit of 45,000 ohms resistance.

The resistance when making 120 revolutions per minute is 2,810 million ohms.

The Signal Officer was down in the cellar, handing over ohms, ampères, short-circuits, and other mysterious trench-stores to his "opposite number.

Madison. OHM, GEORG SIMON, a German physicist, born at Erlangen; discovered the mathematical theory of the electric current, known as Ohm's Law, a law based on experiment, that the strength of the electric current is equal to the electro-motive force divided by the resistance of the wire (1787-1854).

In each multiplier wire I have 500 ohms resistance.

A Bradley tangent galvanometer is used, employing the coil of 160 ohms resistance.

This cell measured, with 25 elements of Leclanche, 40,000 ohms.

On changing the battery to 5 elements the resistance fell instantly to 30 ohms, and there remained.

On again using the current from 25 elements, the resistance instantly returned to 40,000 ohms.

Table C gives some recent results obtained with L B cells, including one whose resistance, with 25 elements Leclanche, was 11,381 times as high as with 8 elements, and which, after standing steadily at 123 ohms (and then at 325 ohms with 1 element), on receiving the current from 25 elements again returned to its previous figure of 1,400,000 ohms.

-+++- | ohms.

In the low state, it may be a few ohms, or even a few hundredths of an ohm.

In the high state, it is the normal working resistance of the cell, usually between 5,000 and 200,000 ohms, but is often up among the millions.

The four bobbins are grouped for tension, and have a total resistance of 30,220 ohms.

Thus arranged, the instrument is capable of making a deflection of one division of 1/50 inch upon a scale placed at a distance of a little more than a yard, with the current produced by one daniell of 10 ohms.
