What is the approximate voltage output of six ordinary flashlight dry cells when connected in parallel?

When dry cells, such as those found in ordinary flashlights, are connected in parallel, the voltage output remains the same as the voltage of a single cell. Each ordinary flashlight dry cell typically has a voltage output of 1.5 volts.

In a parallel connection, while the current capacity can increase (as the total current is the sum of the currents through each cell), the voltage does not add together. Thus, connecting six 1.5 volt cells in parallel will still provide an output of 1.5 volts. This characteristic of parallel circuits is key in understanding the behavior of batteries connected in parallel.

Therefore, the correct answer aligns with the fundamental principles of electrical circuits concerning voltage output in parallel arrangements.
