It is sometimes necessary to use an electrical fuse of smaller amperage than those at hand, and for experimental work this is often the case. A smaller amperage may be readily made from a larger-size wire by making a nick in it with the cutting edge of pliers, or with a knife. The illustration shows how to reduce the size of a 10-ampere fuse to make it five amperes. - Contributed by Louis Litsky, Brooklyn, N. Y.
