What is reverse polarity protection?
All batteries have two terminals, one positive and one negative, and usually they need to be hooked up right for the equipment to work. Some equipment will be damaged if you hook the battery up the wrong way - reverse polarity. Equipment that has reverse polarity protection has something in them which makes them able to stand being hooked up wrong w/o being damaged.

What causes a battery to reverse polarity?
Discharging it to 0V (ie. absolutely empty). And not battery, but "cell" (even a small AA or AAA battery is consider a "cell" - think Duracell).Batteries are usually made up of individual cells (like car batteries, RC batteries etc.), and even if not all of them are discharged completely, if even just one cell reverses polarity, it will do irreversible damage to the battery.
What happens if you switch the ends of the wire coil from one battery terminal to the other?
If you switch the ends of the wire coil from one battery terminal to the other, the direction of the current flow through the coil will reverse. This will cause the magnetic field generated by the coil to also reverse its polarity.
The polarity of an eletromagnet is determined by the?
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.
Where is the starters located on a s 10 truck?
There is only one starter per truck. If you follow the positive battery cable from the battery it will lead to the starter.
What is mean polar?
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
What keep one special battery from failing out of two on the same truck?
any special battery
How can I change the Liftmaster battery?
To change the Liftmaster battery, locate the battery compartment on the back of the opener, remove the old battery, and insert a new one following the correct polarity. Make sure to dispose of the old battery properly.
Which battery should i use for 1963 Ford Falcon The one i have now doesnt seem strong enough...should i use a truck battery?
a 127 should do the job,Wouldnt recommend a truck battery
How would reduce the reverse polarity in magnetization of permanent magnet?
One way to reduce reverse polarity in a permanent magnet is by ensuring it is subjected to strong external magnetic fields in a controlled manner during the manufacturing process. This can help align the magnetic domains in the desired orientation and minimize the chances of reverse magnetization occurring. Additionally, using high-quality materials and adopting proper handling techniques can also help reduce the risk of reverse polarity in permanent magnets.
When diode is connected to ohmmeter What happens?
A: Depends on meter leads voltage polarity and the diode itself orientation to these polarity. One way is should show a low impedance + to anode Reverse the diode it should be hi impedance
