Answer» The correct CHOICE is (b) breadth of the ring slot = (number of turns in a band + 1)diameter of band WIRE + 2constant For explanation: The number of turns in a band is first calculated ALONG with the diameter of band wire. The value of constant is just fixed and on substitution gives the breadth of the ring slot.
