While batteries deliver a steady source of electrical energy at a fixed polarity, connecting batteries together, like individual voltaic cells, allows us to create much higher voltages or amp-hour ratings for whatever application is required.
Industry Why is the current equal when the resistors are in series?
And the reason why is that under direct current, the capacitor saturates. It charges up to some value and then no more current goes through it. So that has a very straightforward interpretation as your electron speeds: if you think about electrons flowing through this thing, and they go faster through one resistor then the other, then the wire in the middle is

Also, current is not the result of charges "pushing" each other; it comes from charges undergoing an electric field. The current increases at fixed voltage, just like the water
Industry When you connect two batteries in series, why doesn''t the middle
When you connect the plus from one battery to the minus of the other, you have a short of the second kind. However, there is no current flowing, as this requires a circuit —a closed loop— so obviously, B does not imply A. As soon you connect the plus from the other battery to the minus of the first also, there is a closed loop, and your short of the second kind

6 Frequently Asked Questions about “Why is the current high when batteries are connected in parallel”
Why does voltage increase when you combine batteries in parallel?
The voltage difference between A A and B B can be seen as the output voltage of the two batteries combined so that's why the voltage doesn't increase when you combine batteries in parallel. To see why every part of the wire is at the same voltage we can look at the water analogy. Connecting two wires together is like joining two canals together.
What happens if a battery is connected in parallel?
When batteries are connected in parallel, you are not increasing the pressure, but you are giving the batteries the possibility to supply more current if the circuit conditions allow it. You can also explain it as table legs. When you add more legs to a table, it CAN hold up more weight but only if you put more weight on to it.
Do parallel batteries supply more current?
The parallel-connected batteries are capable of delivering more current than the series-connected batteries but the current actually delivered will depend on the applied voltage and load resistance. You understand Ohm's Law, but the "parallel batteries supply more current" statement should really be "parallel batteries CAN supply more current".
How does a parallel connection affect voltage?
In a parallel connection, batteries are connected side by side, with their positive terminals connected together and their negative terminals connected together. This results in an increase in the total current, while the voltage across the batteries remains the same. Effects of Parallel Connections on Voltage
Why do batteries need to be added in parallel?
"Because the batteries were originally designed for V volts. But on adding batteries in parallel makes a large amount of repulsion in positive terminals that is felt by both batteries and reduces the amount of charge on each terminal which also decreases the voltage of each battery.
How does a parallel battery system work?
By connecting batteries in parallel, their amp-hour ratings combine, effectively increasing the current capacity without altering the system's voltage. For example, two 12V batteries rated at 100Ah each will yield a system capable of supplying 200Ah at 12V.
