Q1 Wire'A' has a lower melting point than wire'B'.Which wire would u choose to make a fuse to (a) allow more current to pass through and (b) allow less current to pass through?
Give reasons for ur answer

Answer 1

(a) wire A, as wire A has lower melting point so it will not melt soon when more current is passed through it. (b) wire B,as wire B has higher melting point so it will melt soon when more current is passed.so we will use it for passing less current.

Answer 2

Wire 'a' because it holds lower melting point so it will melt and break the circuit whenever a voltage of current pa_ss through it.
