State true or false-`The safe current that can be allowed to pass through a fuse wire is directly proportional to cross sectional area and inversely proportional its length.`

It`s is true , because fuse wire should hai low resistance and high conductances both are full fill by above condition . Conductance = 1/R And R = Lenght / area of cross section It will reversed in conductance case Hope this will help you , cheers !!
