e placed so that one is moveable, andare kept at a certain difference of potential; there is in con-sequence an electrostatic attraction between them. Onthe back of each of these plates is coiled a wire, so thatthe battery-current goes in the two wires in opposite direc-tions; there will then be an… … Let A, A be the discs, B the battery, and 0 the largeresistance. The current from the battery goes through thetwo coils on A, A and through the large resistance in O.Hence if U be the difference of potential at the extremitiesof G in electromagnetic measure, the current-strength isgiven by Hence…
