A wire is carrying a direct current of 20A and a sinusoidal alternating current of peak value 20A. Find the rms value of the resultant current.

A wire is carrying a direct current of 20A and a sinusoidal alternating current of peak value 20A. Find the rms value of the resultant current. Correct Answer 24.5

Direct current = 20A, sinusoidal alternating current of peak value = 20A. The rms value of the combined wave = √(202+202/2) = 24.5A.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.

A telephone switchboard 100 pair cable can be made up with either enameled wire or tinned wire. There will be 400 soldered connections. The cost of soldering a connection on the enameled wire will be P 1.65 on the tinned wire, it will be P 1.15. A 100- pair cable made up with enameled wire cost P 0.55 per linear foot and those made up of tinned wire cost P 0.75 per linear foot. Determine the length of cable run in feet so that the cost of each installation would be the same.

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.
