SECTION - I Q.1) (A) (B) (C) Q.2) (A) (B) (C) [3761]-103 How materials are classified as Conductor, Insulator and Semiconductor. Give two examples of each. An electric pump lifts 60 m3 of water per hour to a height of 25 meter. The pump efficiency is 86% and motor efficiency is 78%. The pump is used for three hours daily. Find energy consumed per week, if one m3 of water is 1000 kg. Explain the charging of Lead Acid Battery with chemical reaction. What are the changes taking place during charging ? OR Obtain the expression for 2 = 1/1 + 1 (t2 t1). An electric furnace is used to melt aluminum. Initial temperature of the solid aluminum is 32oC and its melting point is 680oC. Specific heat capacity of aluminum is 0.95 kJ/kgoK and the heat required to melt 1 kg of aluminum at its melting point is 450 kJ. If the input power drawn by the furnace is 20 kW and its overall efficiency is 60%. Find the mass of aluminum melted per hour. [06] [06] [06] [06] [06] What is Insulation Resistance ? What are the factors on which insulation resistance of a single core cable depends ? [06] 1 P.T.O.
