tromotive force iscalled the volt, and is about the pressure set uid by a Voltacell, so that if a cell has an E. M. F. of 1.4 volts we meanthat it possesses 1.4 times the force of a Volta cell. Cellsare, therefore, rated by their E. M. F. In ^fl36 will befound a table of E. M. F.s of the different… … phuric acid. The silver or lead plate is covered with a fine, powdery deposit of platinum, which gives the surface a rough character, so that the bubbles of hydrogen will not readily adhere to it as they are formed, but rise to the surface of the solution.
