In a series circuit configuration, what happens to the total voltage when additional voltage sources are added?

In a series circuit configuration, when additional voltage sources are added, the total voltage increases because the voltages of each source combine algebraically. In a series connection, the current passing through each component is the same, and each voltage source adds its potential difference to the total voltage across the entire circuit.

For instance, if you have two batteries connected in series, one supplying 1.5 volts and another supplying 3 volts, the total voltage across the circuit is the sum of the voltages from both batteries, resulting in a total of 4.5 volts. This principle applies regardless of the number of voltage sources, as long as they are connected in series. Therefore, the accumulation of voltage from each source leads to an increase in the overall voltage available for the circuit.
