If ten 12-volt batteries are connected in series, what is the resulting voltage?

Explanation:
When batteries are connected in series, their voltages add together. Each of these is 12 volts, so stacking ten of them yields 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 120 volts. The current rating doesn’t increase in a series connection; the same current flows through every battery, and the overall output remains DC. So the resulting voltage is 120 volts DC. (If they were wired in parallel, the voltage would stay 12 V but capacity would increase.)
