Generally speaking, the price of the meter is a subordinate consideration.
The ultimate goal, I submit, is not to optimize just meter by meter but what I call "grape by grape," down to each individual piece of flora and fauna.
A modification of the above meter with some mechanical improvements has been devised by S.
The principles of telegraphy (land, submarine and wireless) and of telephony are discussed in the articles Telegraph and Telephone, and various electrical instruments are treated in separate articles such as Amperemeter; Electrometer; Galvanometer; Voltmeter; Wheatstone'S Bridge; Potentiometer; Meter, Electric; Electrophorus; Leyden Jar; &C.
An electricity meter should therefore have approximately the same accuracy.
