ced is altogether independentof the shape or size of the platesor their distance apart. But if thenature of the plates is changed,the deflection changes. Thus, whilecopper and zinc in dilute sulphuricacid have an E.M.F. of one volt,carbon and zinc show an E.]M. F.of at least 1..5 volts, while… … Fig.273. Principle of commercialvoltmeter We learn, therefore, tliat the E.M.F. of a galvanic cell dependssimply upon the materials of ivhich the cell is composed, and notat all upon the shape, size, or distance apart of the plates. 321.
