If three 1 1/2 volt dry cell batteries are wired in series, what is the total voltage provided by the batteries?

When batteries are connected in series, the total voltage is calculated by simply adding the voltages of each individual battery. In this case, each dry cell battery has a voltage of 1 1/2 volts. With three of these batteries connected in series, the total voltage would be the sum of:

1 1/2 volts + 1 1/2 volts + 1 1/2 volts = 4 1/2 volts.

This makes the total voltage provided by the three batteries equal to 4.5 volts. Connecting batteries in series increases the total voltage while the capacity (amp-hours) remains the same as a single battery.
