Hi:
I would appreciate your assistance for the following questions.
1) Why are batteries in vehicles (sometimes) grounded? What is the purpose? What are the advantages/disadvantages of grounding or not grounding?
2) A lead-acid accumulator exploded when a metal bar fell over it. What could cause the short circuit? Did the metal bar contact simultaneously both the positive and the negative terminal? Or can the short circuit occur with the bar touching only one terminal (positive ort negative) and ground?
Thanks in advance.
