Question 1

In rectangular form, conductance will be written as

Question 2

An. An audio amplifier has a lower cutoff frequency of 20 Hz and upper cutoff frequency of 20 kHz. The amplifier delivers 20 W to a 12

load at 1 kHz. The r.m.s. load voltage at 2 kHzis

Question 3

A conductor has an overall diameter of 20 mm. It is supported on level supports of a span of 160 m. A wind pressure acting on the projected area is 30 kg/m². This wind pressure produces a horizontal shift of 400 mm at the central point. What is the tension in the conductor due to wind load?

Question 4

An industrial consumer has a connected load of 50 kW and his maximum demand is 40 kW. On the average, each machine works for 8 hours a day for 300 working days in a year. The tariff is (Rs. 5000 + Rs. 800 per kW of maximum demand + Rs. 1.15 per kWh of energy consumed). The annual bill of the consumer is

Question 5

A diesel power station has fuel consumption of 0.28 kg per kWh, the calorific value of fuel being 10,000 kcal/kg. If alternator efficiency is 95%, what is the efficiency of the engine?

Question 6

A thermal generating station has an installed capacity of 15 MW and supplies a daily load of 10 MW for 12 hours and 5 MW for remaining 12 hours. The plant capacity factor for this station is

Question 7

A copper voltameter is connected such that a steady current flows in a coil of resistance $Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image132.png$ for 20 minutes. If copper deposited is 0.99 g and E.C.E. of Cu is $Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image133.png$ the amount of heat developed in the coil is

Question 8

Figure shows Wien bridge oscillator. If resistors and capacitors are identical
(i.e. =

and

), then feedback fraction is

Question 9

The equipment in a power station costs Rs. 15,60,000 and has a salvage value of Rs. 60,000 at the end of 25 years. Using diminishing value method, the depreciated value of equipment at the end of 20 years is

Question 10

A resistor of $Description: E:\Gate\SSC-JE Electrical - Part 1\2_D-C-Circuit-final_files\image223.png$ is connected in series with a parallel combination of a number of resistors, each of $Description: E:\Gate\SSC-JE Electrical - Part 1\2_D-C-Circuit-final_files\image223.png$ . If the total resistance of the circuit is $Description: E:\Gate\SSC-JE Electrical - Part 1\2_D-C-Circuit-final_files\image284.png$ the number of resistors in parallel is
