Is there current when the negative poles of two batteries are connected
Why doesn''t the voltage increase when batteries are connected …
If you connect the same load across the terminals of two 1.5-volt batteries connected in parallel, the current through the resistor will still be 1.5 mA, but now each battery only has to supply 0.75 mA of current.
21.2: Electromotive Force
Internal Resistance As noted before, a 12-V truck battery is physically larger, contains more charge and energy, and can deliver a larger current than a 12-V motorcycle battery. Both are lead-acid batteries with identical emf, but, because of its size, the truck battery ...

But when we connect two batteries in series connection the junction point must get neutralize because here meets positive and negative poles of two batteries. Hence the voltage across series connection should be the same voltage as the voltage of individual battery. how the voltages of two batteries get added in this case?? $endgroup$

What Happens If You Connect Positive to Negative on a Car Battery
Short Circuit and Damage If you connect the positive terminal of one battery to the negative terminal of another battery, it will result in a short circuit.A short circuit occurs when an electrical current flows through a path that has little or no resistance, causing a surge

Same way, a lamp lights up if you connect it to the both terminals of a say 12V battery. Connecting one of the battery terminals (pick either of them) to earth will do nothing special. There will still be 12V between battery terminals, and current will only flow through the lamp if it is connected to battery terminals.

1) Two thin conducting wires are used to connect very large conducting plates to opposite poles of a battery. Chemical reactions within the battery produce an emf £ that "pushes" one electron after another onto the wire connected to the negative terminal of the battery, and "pulls" one electron after another from the wire connected to the positive terminal of …

Final Thoughts Connecting batteries in parallel is a great way to extend the runtime of your backup power supply. It increases the amp-hour capacity of the battery bank, allowing you to power your devices for a longer …
Current flow from positive to positive between batteries?
If you have two batteries with different voltages, let''s say 12 and 9 V, and you connect the negative terminals while you put a LED or whatever between the positive terminals, there will be current flow. I reason that is because there is a potential difference even though both terminals are positive.
