A fully charged car battery typically measures around 12.6 volts, with a normal voltage range of 12.4 to 12.7 volts.. It is important to note that the voltage of a car battery can vary depending on several factors.
Before the spark, there is no current at all, only a voltage (potential difference) between two points. Arc discharge happens when the voltage is high enough to overcome the gap, and then continues when conductors are drawn apart until the plasma dissipates. This depends on how large the gap is; you can easily draw visible sparks from a 12V power supply …

So in these applications, the power stages have to handle big input current. This reference designdelivers a low input voltage high current boost application with a combination of the ...
Well, 110V is not really high voltage, just more than a 9V battery. 10,000 volts acts more like "high voltage" but 100,000 volts is even better (for arcs, lighting gas tube lights at a distance, etc). Not that you would really try the experiment, but metal shorting a power outlet will give you a burn or a fire depending on how quickly the ...
The total voltage drop across the internal resistance is again given by Ohm''s law: $$ V_s = V_0/R_s $$ The net effect of this is that the total voltage you''ll see across the terminals of the battery will drop as you draw more current from the battery. At some point, the voltage will reach zero -- this is when you short the battery terminals ...
You can have a high potential difference (which is what voltage is), and a low current, simply by having a high resistance in place to block that current. Think of it like a water hose turned on full blast, with a hose gun …
Low voltage battery systems (<60V) have to manage more current which requires thicker cabling and more copper to transfer energy back to the system; this increases cost. Efficiency is gained through high-voltage systems because the architecture can support the same amount of power with smaller cabling and less copper.
A car battery has very low internal resistance, generally less than 0.1 ohm. That means if you short its terminals, the entire 12V is placed across the battery''s internal resistance. 12V/.1 ohm …

As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross-sectional area in copper …

The internal resistance of the battery is high? That would explain why the voltage is high when there is no current but why there is no voltage when there is current. The more current is drawn by the battery, the more voltage is dropped across the internal resistance and therefore the less voltage actually appears on the battery terminals.

Guarantee is high voltage with provided current.
