Which of the following statement(s) is/are TRUE? I. Fuse is generally placed in series with the device. II. Fuse is generally placed in parallel with the device. III. Fuse wire has a high melting point. Correct Answer Only I

A fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current.  Fuse is generally placed in series with the device so that when the fuse blows or open, it will open the entire circuit and stop current through the main component.

Mostly fuse wire has a low melting point. If it is having a high melting point, current can flow through the main component because fuse wire could not due to the high melting point.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Specialty steel and wire ropes maker Usha Martin's decision to sell one of its core businesses - steelmaking - to prune outstanding debt, marks the rare instance of an Indian corporate borrower meeting its loan obligations through divestment. The slump sale is a milestone in the six-decade history of the Kolkata-based company, whose board on Saturday approved the divestment of its one million ton steel business in favor of Tata Steel for Rs 4,600 crore.  Courses of action: I. Proceeds will be used to ‘first repay existing lenders of the company’. Usha Martin will retain a profitable wire ropes unit as residual business, and has plans to scale it up significantly.  II. As part of the transaction, Usha Martin has entered into a five-year deal with The Tatas for sale of steel at market price to the wire-ropes business.  III. Usha Martin is among the top four wire rope players globally. With oil prices going up and strong trend in demand in Europe, the Ebitda in the wire-ropes business has improved.
