What reading level is Short Lectures to Electrical Artisans Being a Course of Experimental Lectures D book?
To quickly assess the difficulty of the text, read a short excerpt:
Divide this weight measured in grams by the time in seconds during which the experiment continued. This gives the deposit of copper per second. Divide this again by number '000327, and it gives us the ampere current which was passing through the galvanometer.
Call the ampere current A. Then, corresponding to this, we observed a certain deflection of the needle, say D, divisions on the tangent scale. Then A divided by D gives us the ampere current which would produce a deflection of one tangent ...division. This number is called the constant of the galvanometer. In any other case, if we obtain a certain observed deflection with any current, then the value of the deflection in tangent divisions, multiplied by the constant for the instrument, gives us the value of that current in amperes.
42. A tangent galvanometer is an instrument for measuring the strength of a current by comparing the mag- netic field produced by that current at the centre of a circular conductor with the magnetic field due to the earth.
