How much electrical voltage is needed to blow the terminals in a car battery?
WoodStockNZL
It's not how much voltage..that's set by the battery around 12.7 volts..it's the time/current. If a very fine wire is connected between the 2 terms the wire will disintegrate similar to a fuse but a higher temperature. A heavy cable capable of carrying several hundres amps ..like 4/0..will get hot instantly..maybe enough for it to melt. If it doesn't melt the battery's internal components will reach a critical temp..the plates will quickly bow and bend, fluids and gels will boil and the terminals will blow off the battery or the battery will explode. If you're thinking of trying this..make out a will first. The rest of us will read of your demise in the Sun. This reaction occurs extremely fast...milliseconds...

What parts are needed to create a circuit?
A basic electrical circuit needs a voltage supply (battery or household outlet), wiring to carry electrons to and from the voltage supply to the load, and a load (motor, light, heat element, stereo, blender, whatever).
What is electrical cable size for 18.5kw?
To answer this question the voltage is needed.
Where is the voltage regulator located on a 1995 Saturn dohc the starter battery and alternator all went at the same time you have replaced all 3 but it is still losing power any help please?
The voltage regulator for a 1995 Saturn SL2 is in the alternator. Check your charging voltage after the engine is started and has run a few minutes. Should be better than 14 to 15 volts at the battery terminals. Make sure the battery terminals are clean and tight. Had a neighbor replace alternator, battery and starter and all he needed was a good connection to the battery, which I supplied. To load test the alternator, turn on the headlights on high beam, heater fan to top speed and the rear window defoger. Battery voltage should not drop more than 0.25 volts with the engine turning a little faster than idle. Hope this helps.
Function of the battery?
The function of a battery is to provide electrical energy to devices which are connected to it.
Why does a battery charger produces a higher voltage than the battery being charged?
Battery chargers generally operate at the same voltage as the voltage as the battery they are charging. They usually vary the amperage they feed into the battery to recharge it. A trickle charger usually only feeds a few amps into a battery to recharge it slowly over time. A fast charger feeds more amps for less time to bring the battery to full charge faster. Automotive alternators are the only charging systems that I am familiar with that generate more voltage than the battery they are charging. That's because they have to run the car AND recharge the battery at the same time. Car alternators can vary their amperage and voltage outputs to allow for the varying demands of the car and all of it's electrical devices and recharge the battery as needed.
How long can a battery power a 44 watt light bulb?
To answer this question the amp hour rating of the battery is needed along with the voltage of the battery or bulb.
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
How does a battery supply energy to a circuit?
The battery helps the wires complete the curcuit.
Why does the battery voltage fluctuate from 14.4 volts to 12.6 volts and back again while driving?
The battery in your car does not constantly charge while driving. Electricity is needed to run the headlights, starter, radio, etc. In order to save wear on the alternator/generator, the battery is sometimes used to power these electrical devices as your car's internal sensors see fit. When the battery's charge drops below a certain voltage, the alternator kicks in again to keep the battery at its optimum level.
What jobs dose a battery do in the circuit?
The purpose of the battery in a circuit is to wive energy to the circuit
Can a 0.9V 400MA solar panel be used to charge 2 AA batteries?
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
Will any 12v battery charge work?
According to the magnitude of said current will be the time needed for charging. For there to be a current flow to the battery, the charger must provide a voltage (voltage) higher than the battery, this is the reason why we can not charge a 12V battery from another. Or at least, could not, as we shall see later.
