What is a positive terminal on a battery?
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
What happens if you connect a short copper wire to both the positive and negative terminals of a battery and why?
The wire will get hot, the temperature it gets up to will depend on the ampere of the battery and size of wire. The wire can get hot enough to causes burns or start a fire if the battery is large enough. Why this happens is because you have shorted the battery out. The power comes out of the positive post and back in the negative post. When you short it out the power can flow from one post to the other very quickly causing the short to get hot, due to the amount of flow.
What happens when you stick two 9 volt batteries together?
If you connect positive to positive and negative to negative you will have a 9V battery with twice the current capacity in milliampere hrs than a single batteries. The load then goes between positive and negative paralleled terminals. If you connect one negative of one battery to one positive of the other battery and put the load between the remaining negative and positive terminals you have created an 18 V battery with the same milliampere hr rating as a single battery. If you connect one negative to positive of other battery and the negative of that battery to the positive of the first battery then both batteries with quickly drain and get hot in the process. Contrary to folklore or urban lefends, they do not explode.
Does a hot water heater element have a positive and negative?
For an electric water heater on alternating current, there is not 'positive' or 'negative'. There should be terminals labeled hot and neutral, though.
Is the red wire the negitave on your battery?
No Red is positive and it is hot
What is the name of the positive battery cable for a 1999 Chrysler Concorde?
Positive, hot, or + red cable.
What causes a car battery to get hot?
poss alternator fault
Why battery positive is hot?
simple answer is ground wire is not properly installed
Which wire is positive or negative in hot power lithium polymer battery?
Red is positive, Black is the negative
What is the condition that causes positive mass balance?
When it is hot and there is no precipation
How do you hook up your cooling fan to your battery?
A person can hook up a cooling fan to a battery by connecting the hot or positive lead to the positive side of the battery. The negative lead wire is then connected to the negative side of the battery.
What happens when hooking 2 9 volt batteries together?
Interconnecting Two 9 Volt BatteriesWhat happens "when hooking 2 9 volt batteries together" depends on HOW they are connected together. IF you connect the Negative terminals together, AND the Positive terminals together, then nothing happens other than creating a 9 volt battery capable of providing twice the current [measured in Milliamps (mA), or Amps (A)].On the other hand, IF the batteries are connected with the Positive terminals to the Negative terminals of the other, THEN you will have created a very serious and possibly hazardous condition!!!!!When connected in this manner, the full current of both batteries flows, basically a full short circuit condition, and both batteries will very quickly heat up to the point of self destruction, and very likely to explode.Even it they do not explode, they will certainly become hot enough to severely burn you, and start a fire if they are in near proximity to anything combustible.Therefore, DO NOT interconnect any batteries, with both of their Positive terminals to the other's Negative without a load [electricity using device within the the circuit] to limit the current flow.If you connect the positive terminal of one battery to the negative terminal of the other and then put the load between the remaining positive and negative terminals on each battery you then have an 18 V battery. This is connecting the batteries in series.
