Q. Different kinds of high-tension fuses and low-tension fuses ?
Ans: There are two kinds of fuses they are
a) L.V Fuses - 1) HRC cartridge fuses. - 2) Semi enclosed re-wirable fuses
b) H.V Fuses - 1) Liquid type - 2) High voltage HRC fuses
Q. Let m 1 (t) and m 2 (t) be two message signals, and let u 1 (t) and u 2 (t) be the corresponding modulated versions. (a) When the combined message signal m 1 (t) + m 2 (t) DS
