A standard conductor have three layers of wire. What will be the diameter of stranded conductor if diameter of each strand is 5 mm?
d Explanation: If the diameter of each strand is ‘d’ then diameter of the standard conductor will be (2n + 1)d. ‘n’ is number of layers.

Fuel other than natural gas i.e. solid and liquid fuels can be used in _______
b Explanation: In closed cycle gas turbine power plant the working medium is heated externally and the fuel is not mixed with working fluid. This ensures the use of any fuel such as inferior type or solid type fuel.

Monthly consumption of a consumer is 500KWh. What will be the monthly bill at the following rate? First 100 unit Rs 0.6/KWh Next 100 units Rs 0.5/KWh Remaining units Rs 0.4/KWh
c Explanation: 500 KWh = (100 +100 + 300) KWh Bill for one month consumption = (100×0.6 + 100×0.5 + 300×0.4) Rupees = 230 Rupees
c
See lessExplanation: 500 KWh = (100 +100 + 300) KWh
Bill for one month consumption
= (100×0.6 + 100×0.5 + 300×0.4) Rupees
= 230 Rupees
If an industrial consumer consumes 50KW for 4 hours, 300KW for 15 hours and 60KW for 5 hours daily and the tariff rate is Rs 5/KWh. What is the energy consumption in a month of 30 days?
a Explanation: Energy Consumed in one day = (50×4 + 300×15 + 60×5)KWh = 5000 KWh Energy Consumed in one month = 5000× 30 = 150000 KWh Hence, Charge on one month = 150000 × 5 =750000 Rupees.
a
See lessExplanation: Energy Consumed in one day = (50×4 + 300×15 + 60×5)KWh = 5000 KWh
Energy Consumed in one month = 5000× 30
= 150000 KWh
Hence, Charge on one month = 150000 × 5
=750000 Rupees.
Identify the type of tariff the consumer is charged Rs 4 per unit if the consumer does not exceed 50 KWh, Rs 3.50 per unit if the consumer does not exceed 50 KWh but less than 200 kilowatt hour, and Rs 3 per KWh if consumer exceeds 200 kilowatt hour.
d Explanation: Step rate tariff is a group of flat rate tariff of decreasing unit charges for higher range of conception. Charges per KWh are reduced for increas in power consumption above different predefined step levels. This type of tariff takes into account the fact of lower generation cost goinRead more

the fact of lower generation cost going to higher energy consumption consequent to
improvement of load factor

In which of the following reactors material converted into fissile materials is more than fissile material consumed?
d Explanation: Burner reactor or thermal reactor is designed only to consume fissile materials and to give heat energy. Converter reactor converts fertile material into fissile material but the rate of conversion is slower than rate of conception. Only breeder reactor from above options is such a reRead more

Heat energy generated in per unit volume of reactor core in thermal reactor is ___________
a Explanation: In fast reactors fission occurs due to fast moving neutrons. Hence, the rate of fission reaction is high and the heat energy generated is also very high. In thermal reactor moderator is used to slow down the neutrons and to make the fission in much more controlled way. So, heat generaRead more
