Current

The current in a circuit is determined by the voltage of the circuit and the resistance of the circuit. When batteries are wired in series, the voltage of the circuit increases, but the resistance remains the same. Therefore, the current in the circuit remains the same. Similarly, when batteries are wired in parallel, the voltage of the circuit remains the same, but the resistance decreases. Therefore, the current in the circuit remains the same.

This principle is important in understanding how batteries work. When batteries are wired in series, the voltage of the battery pack increases, which can be used to power devices that require a higher voltage. When batteries are wired in parallel, the capacity of the battery pack increases, which can be used to power devices for a longer period of time.

For example, a series connection of batteries is often used in flashlights and other portable devices that require a higher voltage to operate. A parallel connection of batteries is often used in laptop computers and other devices that require a longer runtime.
