he explains by saying imagine there''s a guy walking around the circuit and you record the voltage rises and drops so +20 for a battery -10v and -10v for two resistors, but he has never done this with a parallel circuit let alone one with two batteries, its an assignment to make us learn by ourselves, something about learning the same thing in different ways
When two batteries are connected in series, the total voltage becomes the sum of the individual voltages, while the total current remains the same. In the given example, Battery A and Battery B each have a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage is 12 volts, and the total current remains 2 amps.
The battery does not provide twice the current, two batteries provides the same current. Overall current is twice as you have two batteries instead of one.
The "internal resistance" of each battery matters; when you put them in parallel, the internal resistances are effectively in parallel, and thus halved. Oh, and "provide twice the current" should not be read as "will always output twice the current" - current draw is still determined by the circuit connected.
That gives you a ballpark estimate of the current that it is running at for that time. The voltages of the two batteries add in series, which is why you get about 3.3 to 3.0V with fresh alkaline D cells.
Two different batteries have two different chemical flows . Electrons that might leave the anode to go to the cathode of the other battery cannot close the chemical circuit of the parent cell because the ions have no reason to move as no charge has gone to the copper cathode of the original cell.
Connecting batteries in series will increase the voltage and keep current capacity constant. When you connect batteries in series : Connecting batteries in parallel will increase the current and keep voltage constant. You can use combination of connecting batteries in series or parallel to achieve your desired current capacity and voltage margin.

$begingroup$ when connecting the 2 batteries in parallel it''s equivalence to offering a higher capacity battery for the same voltage the C rating is the maximum current the battery can source without a series damage to it''s performance with respect to it''s capacity so 300mah battery can source 300 milliamps of current for an hour but it can source a current of …
However, connecting batteries in parallel will increase the amperage or amp hours. This is important because it means that your devices will be able to run for a longer period of time before the batteries need to be recharged. To connect two 12 volt batteries in parallel, you will need: Two 12 volt batteries;
Current capacity is equal to the lowest current capacity between batteries, as it''s a property of battery, then if all batteries are same, current capacity is same as current capacity of each battery: Max Current Load = 2A $endgroup$
The battery does not provide twice the current, two batteries provides the same current. Overall current is twice as you have two batteries instead of one.
Most coin cell batteries have a ridiculously high internal resistance. If you''ve ever opened one of those small key chain led lights they usually don''t even have a series resistor with the LED, they simply rely on the battery''s internal resistance to limit the LED current. $endgroup$ –
Of course, it''s not always the case, but in simple circuits (like the one with two batteries), it surely is. If you had several sources, more than 3, you should consider all batteries with same poles together, until you get two sources with opposite poles, and again you can use the same logic for circuit. But I will suggest learning Kirchhoff ...
Although it is never advisable to connect two non identical batteries in parallel because it does not make any sense it is useless and may destroy the batteries. In short, when two non-identical batteries are connected in parallel, current will flow from higher voltage battery to lower voltage battery. Which is not good. Small voltage ...
The maximum current depends very much on the chemistry of the battery. The capacity of the three main (no Lithium) batteries is approximately: Zinc-Carbon: 540mAh; Alkaline: ~1000mAh; NiMH: ~900mAh; The current limit and capacity of any specific battery can be found in its datasheet. For instance, the Duracell MN2400 has the following nice graph:

I have to charge two 12 V, 184 Ah lead-acid batteries in a series circuit. I have read that the provided current should be the 10% of the Ah rating of the battery, e.g. in this case it would be 18.4 A for a single battery. If this "10%" statement is true, would it be the 10% of 185 Ah or 185 + 185 Ah?
As the battery is discharged, ions move from one electrode to the other, and the chemical reaction proceeds until one of the electrodes is used up. Thinking about two batteries next to each other, linked by one wire-- there is no voltage between the two batteries, so there is no force to drive electrons. In each battery, the electrostatic force ...
Current means that an electric charge is flowing through a material – a wire, for example, that connects the positive and negative terminals of a battery via a consumer. Here''s an analogy to illustrate the basic principle: Imagine two buckets, one of which is higher than the other. The higher bucket is full of water, the lower one is empty, and the buckets are connected by a tube. …
