which it is connected. The unit of P. D. may be taken for practical purposes as theelectrical pressure produced by a simple galvanic cell consisting ofzinc and copper immersed in dilute sulphuric acid. It is named avolt in honor of Volta. 41. The Electromotive Forces of Galvanic Cells. When… … Fig. 43. Illustrating Princi-ple of Common Voltmeter. 45 36 ELEClRICITY AND MAGNETISM nature of the plates is changed, the deflection changes. Thus, whilecopper and zinc in dilute sulphuric acid have an E. M. F. of one volt,carbon and zinc show an E. M. F. of at least 1.5 volts, while carbon…
