Depends where you put it. Like if you put in on your tongue it will defiantly hurt.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
12 volt
It can be done with 90% efficiency.
no
Generally, there will be a 12+ volt rail, a 5+ volt rail and often a 3+ volt rail.
A 12 volt battery will not hurt you BUT any POWER supply (especially a 230 Volt one) has the potential to harm you.
12 volt
No, you should not jump start a 6-volt car system with a 12-volt system, as this can damage the 6-volt electrical components. The higher voltage can overload the 6-volt battery and other electrical systems, potentially causing serious harm. If you need to start a 6-volt system, use a compatible 6-volt battery or a specialized jump starter designed for that voltage.
12 volt
You would wire them in "Parallel". That means positive post to positive post and negative to negative. Two 12 volt batteries wired this way doubles the capacity and amperage capability of the system. It does not cause any harm to the electrical system as the system sees them as one big battery.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
12 Volt
Definately 12 volt.
1971s had 12-volt systems.
use two 12 volt batteries in series.
It is 12 volts.
