AI Thread Summary
Automotive batteries, despite their nominal 12 V d.c. voltage, pose significant safety hazards due to their ability to deliver high currents, often exceeding 200 amperes. A short circuit can generate enough current to vaporize metal objects, creating dangerous sparks. Additionally, these sparks can ignite hydrogen gas released during the battery's chemical reactions, leading to potential explosions. The discussion also highlights concerns about users seeking quick answers without doing their own research, indicating a misuse of forum resources. Understanding these hazards is crucial for safe handling and maintenance of automotive batteries.

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 !
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'What happens if shielded cable has short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
