When you add two batteries in series the potentials (voltage) are added because since the same charge is moved twice each time thru the same voltage (potential) the total work done is 2 * V but the current flow remains the same. What are the advantages of connecting the batteries in parallel?
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
When two identical batteries are connected in parallel it will double the current capacity and the output voltage remains the same as a single battery. For example, suppose two batteries of same rating i.e. 1800 mAh, 12 V are connected in parallel, the output voltage of parallel circuit is remain 12 V butt current capacity becomes 3600 mAh.
Connecting batteries of different voltages in parallel primary (disposable) batteries – they are not designed to take a charge and so the lower voltage battery is likely to overheat, it may leak or bulge and in extreme circumstances where the voltages are very different, it may explode. Which way does current flow with two batteries?
If the second battery (the lower voltage one) is a rechargeable, then it will be charged by the first one, again until the two have the same voltage. In this case the end voltage will be intermediate between the two starting voltages.
The chemicals in a battery litterally strip charge away from one terminal and deposite charge on the other. In general, the more surface area the chemicals have to deposit charge onto, and take charge away from, the higher the current the battery can produce.
3.3: Networks of Batteries and Resistors

12.4: Magnetic Force between Two Parallel Currents
The ratio F/l is the force per unit length between two parallel currents (I_1) and (I_2) separated by a distance r.The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and other plasmas. The force exists whether the currents are in wires or not.
What happens if an AC voltage is applied to a battery?
$begingroup$ No, AC can''t be used to charge a battery. A chemical battery is inherently DC, and must have a net DC to current to charge it. If the peaks vary too much from the average DC, then the battery can be damaged. Negative current …

$begingroup$ Will have to come back later with an answer class explanation, but essentially the contributions of two senders simply add where they pass each other, the challenge is at the ends. If you know what you are sending you can subtract that and see what the other person sent. The catch is transmission line effects and the possibility of seeing a …

Current flow from positive to positive between batteries?
If you connect two positive but non-equal voltage nodes together, current will flow between them. Calling something "positive" only means that it has a higher voltage …
What would happen if I connect two different DC …
This would apply for e.g. batteries or similar simple voltage source. With two switching supplies though, as W5V0 has noted, the resultant voltage will likely be the higher of the two, as the lower rail cannot sink current (due to the diode) …
Battery Basics: Series & Parallel Connections for Voltage & Current …
In a parallel connection, the total current is the sum of the individual currents of each battery. This means that if two batteries with currents of 2 amps and 3 amps are connected in parallel, the total current would be 5 amps.
What happens when there are 2 batteries in a circuit?
Which way does current flow with two batteries? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current …
What Happens If You Connect Different Batteries in Parallel?
When you connect batteries in parallel, the voltage of each battery remains the same, but the current capacity is increased. This is because the total resistance of the circuit decreases, allowing more current to flow. However, if you connect batteries with different voltages in parallel, they will try to equalize their voltages and this can ...

Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure (PageIndex{7}): Two resistors connected in series with a battery.

3. Battery bank wiring
It matters how a battery bank is wired into the system. When wiring a battery bank, it is easy to make a mistake. One of the most common mistakes is to parallel all the batteries together and then connect one side of the parallel battery bank to the electrical installation. As indicated in the image on the right.
Different voltage sources in parallel
If A was current limited, then it would pull A down to 5v, or a little higher as determined by its charging voltage. If A was a very low impedance source, and B was a small battery, it would fry the battery. If B was a power supply that couldn''t sink current, then ''A would win'' and could take the terminal voltage up to 10v. If that 10v let the ...

Two batteries in parallel: why they deliver "twice the current …
Batteries in parallel, powering the same load as before, will run it for for about twice as long. Think of it like this: For parallel batteries, $Delta Q$ is same for each, but $I$ is half per each (Because they both supply the same load with equal -half- contribution at the same time). Yields $Delta t_{new} = frac{Delta Q}{(I/2)} = 2 ...
