Result
The measured voltage corresponds in each case to the sum of the voltages of the individual cells (1.1v) a higher voltage can be obtained by connecting galvanic cells in series
Comparison with the voltage from cells connected in parallel
Connect zinc electrodes 1 and 3 and copper electrodes 2 and 4 each with a short connecting cord as
show in fig.3 Measure the voltage between electrodes 1 and 4 (or also between 1 and 2 or 3 and 4)
Result
When galvanic cells are connected in parallel there is no change in voltage
