Free QuoteParallel, positive with positive and negative with negative. 2 things connected with a wire will try to be at the same voltage/potential. If you connect 2 batteries with different charge states (let''s
Free QuoteA battery's positive terminal does have a positive potential. ie, a test positive charge will repel it and a test negative charge will attract it. Vice versa for negative terminal. From the paper below (Section 1.2.1), it seems abundantly clear that the battery will have positive and negative potential on respective terminals.
If the other end of the resistor is connected to the positive pole of the battery, the extra electrons will want to travel from the resistor to the positive pole of the battery following the charge density gradient. Now the chemical process within the battery is "triggered" and these electrons are again "moved" to the negative pole of the battery.
The positive side of a battery is only "positive" in relation to the "negative" terminal of the same battery. When you hook a wire from the positive terminal of the first battery to the negative terminal of the second, a very small amount of current will flow until the potential difference reaches zero.
In this structure, the negative (-) pole also serves as the container. This means that holes can open up in the container and fluid spill out due to excessive discharge if accidentally left on for too long. So we need to be careful. These batteries have a long history and are cheap and popular.
If electrons make one side of the battery negative, then the other side is lacking those electrons and wants them. Because the positive terminal is lacking those electrons it has a much more positive voltage. It likely has a lot more protons (which are positive) than the negative side of the battery.
Now the chemical process within the battery is "triggered" and these electrons are again "moved" to the negative pole of the battery. So, now you have a circuit the electrons go around. So electrons do flow out of the negative side. The positive sign indicates this side is positively charged compared to the negative side.
