What are the two types of anti-static bags?

Answer 1

Anti-ESD Shielding: coated in a conductive material (commonly nickel), usually gray

Question 2

What are the two most common fuse ratings, and what can happen if the fuse is fitted too high or too low?

If a fuse is fitted too low it won’t blow when needed and will pass too much current.
