How does connecting transformers in series affect voltage?

When transformers are connected in series, their voltages add together. This means that if multiple transformers are connected in such a configuration, the total output voltage will be the sum of the voltages produced by each transformer. For instance, if one transformer produces 120 volts and another produces 240 volts, connecting them in series will yield a total output of 360 volts.

This principle relies on the concept of transformer ratios, where each transformer can be designed to step up (increase) the voltage or step down (decrease) the voltage based on its turns ratio. Hence, in a series connection, if the transformers are all set to increase voltage, the combined effect will lead to a higher overall voltage.

The correct answer reflects the fundamental operation of transformers in a series configuration, emphasizing their ability to increase total voltage output effectively.
