Ответ:
The right answer is> 7.5V.A series circuit is a circuit in which the various components are placed one after another offering only one path for the current.<
Explanation:
When several cells are connected in series, the total voltage will be the sum of the voltages of each cell, is 5 cells of 1.5V or 7.5Volts.
