Electricity needs to be a complete circuit to operate. current leaves the positive side and flows through the wires, into the operated device, out the other side and returns to the battery. Without the return or allowing the current to flow nothing happens.
they do because like magnets we have negative and positive ,negative and negative repel and vise verse but positive and negative attract
" Anode " is generally refer to POSITIVE. Cathode generally refer to NEGATIVE. But these terms are use for different applications ( For example: you wouldn't refer to the POSITIVE side of a battery as ANODE or NEGATIVE side as CATHODE, it commonly refer as positive or negative when you are dealing with battery application etc. )
They put a +(positive) and -(negative) on each side. The + matches with a - and vice versa.
Yes you can. Connect the chargers positive lead to the positive of one battery, then the negative side of that battery to the positive side of the other battery, then connect the negative lead of the charger to the negative of the second battery. Double check all your connections and turn on the charger.
because batteries works on the principle of electron charge and an electron can have either a more positive or negative charge but the electron wants to have an equal amount of pos. and neg. charge so when batteries are simply they pull the positive charge to one side and negative to the other side and when they come together with a conductor(wire) it creates a current which does the "work" for you. The voltage of the battery pretty much lets you know how strongly the battery wants to create equality between each side thus more current.
Large side is negative
Negative side
In order to connect 4-6 volt batteries and end up with 12volts you will need to understand parallel and series connections. to connect two batteries in parallel you would connect the positive side of one battery to the positive side of the other battery; and the negative side of one battery to the negative of the other battery. doing this will not change the voltage. to connect in series you connect the positive of one battery to the negative of the other battery. doing this will increase the voltage;in this example you will end up with 12v. 6+6=12. when you stack batteries in a 2-cell flashlight that is connecting the batteries in series. The answer to the question is: connect two batteries in series; then connect the other two batteries in series. after this is done connect the two pairs of batteries in parallel. If you think of it visually you would have two batteries wide and two batteries tall.
With the two batteries side by side connect a jumper wire from the positive post on one battery to the negative post on the other. The remaining neg and pos posts on each battery will supply the 24V your looking for.
Connect them in series. With the 2 batteries sitting side by side just connect the negative terminal (-) on battery # 1 to the positive terminal (+) of battery # 2. Now connect the red hot cable to the positive terminal of battery # 1. Then connect the negative black cable to battery #2. You will have 12 volts but the amperage of only 1 battery.
Re-check the batteries and verify that the positive sides are down; the positive side are the flat sides; the curvy sides are the negative sides, which will face (come in direct contact with) the circuit board contacts. I drained two brand new batteries by putting them in the wrong way (positive side up!)
The positive
