Connecting Batteries in Series

When batteries are connected in a series, the positive terminal of one battery is connected to the negative terminal of the next battery. The negative terminal of the first battery and the positive terminal of the last battery are used to connect to the circuit.

- The voltage of the batteries adds up: When batteries are connected in series, their voltages add up. For example, if two 1.5V batteries are connected in series, the voltage across the circuit will be 3V.
- The current through all batteries is the same: When batteries are connected in series, the current through all batteries is the same. This is because there is only one path for the current to flow through.
- The total capacity of the batteries remains the same: When batteries are connected in series, the total capacity remains the same. For example, if two batteries with a capacity of 1000mAh are connected in series, the total capacity of the circuit will still be 1000mAh.

Connecting Batteries in Parallel

When batteries are connected in parallel, the positive terminals of all batteries are connected together, and the negative terminals are connected together. The positive and negative terminals of the battery pack are then connected to the circuit.

- The voltage of the batteries remains the same: When batteries are connected in parallel, the voltage across the circuit remains the same as the voltage of the individual batteries.
- The current through each battery is divided: When batteries are connected in parallel, the current through each battery is divided. For example, if two batteries are connected in parallel and the circuit draws 2A of current, each battery will supply 1A of current.
- The total capacity of the batteries adds up: When batteries are connected in parallel, the total capacity adds up. For example, if two batteries with a capacity of 1000mAh are connected in parallel, the total capacity of the circuit will be 2000mAh.

Conclusion

In conclusion, batteries are generally connected in series when a higher voltage is required, and they are connected in parallel when a longer runtime is required. It is important to note that connecting batteries in series or parallel can impact the overall performance of the battery pack, and it is important to use batteries with similar characteristics and capacities when building a battery pack.

When the batteries are connected in series connection passes through the current while connected in series connection. for example take two bulbs and connect one side wire that side only another wire connect and take another wire connect with second wire then take another one and freshly take wire connect it and keep the bulbs then switch on when that two bulbs are glows then it is connected in series.
