Summary

[edit]
Description
English: In the Grove's cell the copper plate in the Daniell's cell is replaced by a sheet of platinum, p, and the solution of copper sulphate by strong nitric acid. Dilute sulphuric acid, in the proportion of about one pint of acid to ten pints of water, is used in place of zinc sulphate solution, since, with the Grove's cell, we wish to obtain the highest E. M. F., and the lowest resistance rather than very great constancy. The E. M. F. is about 1.93 volts.
