Electrical Safety: Explaining Automotive Battery Hazards

[usmanmasood]

Sir Iam in great need of this answer

1.An automotive battery currently operates at a nominal 12 V d.c.This voltage level is normally considered inherently safe.Explain why the automotive battery still represents a safety hazard.(at least 100 words).

Though it's low-voltage, a car battery can provide an enormous amount of current, often more than 200 amperes. If you drop a screwdriver across the terminals, for example, enough current will flow to vaporize the screwdriver and splatter molten metal all over the unfortunate mechanic.

A significant danger is that sparks resulting from a short will ignite free Hydrogen released by the chemical reaction inside the battery.

This really looks like a blatant effort to get us to do your homework. I do not think this is proper use of the forums. With a bit of effort on your part all of this information is available.

"at least 100 words" ? Sure looks like you're trying to get someone to do your homework for you !
