Thirty 1.5 volt batteries connected in parallel is equivalent to how many volts?

When batteries are connected in parallel, the voltage remains the same as that of an individual battery. The main purpose of connecting batteries in parallel is to increase the available current capacity while maintaining the same voltage level.

In this scenario, each battery has a voltage of 1.5 volts. Regardless of how many batteries are connected in parallel—in this case, thirty—the total voltage output of the configuration remains 1.5 volts because they share the same voltage level.

Thus, the correct understanding is that the overall voltage of the parallel connection of thirty 1.5-volt batteries will still be 1.5 volts, not the product or a sum that might suggest a higher voltage, such as 45 volts or any other option. This preserves the integrity of the voltage provided by each battery while allowing more current to be drawn if needed.
