If five dry cells are connected in series, what will the terminal voltage be in relation to one cell?

When five dry cells are connected in series, the total terminal voltage across all the cells is the sum of the individual voltages of each cell. Each dry cell typically has a standard voltage (for example, 1.5 volts for an alkaline cell). Therefore, if one cell has a voltage of 1.5 volts, five cells in series will combine their voltages, resulting in:

1.5 volts (one cell) + 1.5 volts (second cell) + 1.5 volts (third cell) + 1.5 volts (fourth cell) + 1.5 volts (fifth cell) = 7.5 volts total.

This means the terminal voltage of five cells connected in series is five times the voltage of a single cell, demonstrating the additive property of voltage in series circuits. This principle is foundational in electrical circuits, where the voltage adds up when components are connected in series, leading to a higher total voltage output.
