Explanation / Answer

1) generator works on faraday's law of electromagnetic inducation .when coil is rotated in a magnetic field by some mechanical means magnetic flux is changed through the coil and consequently emf is induced in the coil.

2)three techniques are there

a) conventional steam- Oil is burned to heat water to create steam to generate electricity.

b) combustion turbine- Oil is burned under preassure to produce hot exhaust gases which apin a turbine to generate electricity.

c) combined -cycle technology - Oil is first combusted in a combustion turbine, using the heated exhaust gases to generate electricity . After these exhaust gases are recovered, they heat water in a boiyler,creating steam to drive a second turbine.

3) electricity generation is 65% from oil,27%from natural gas,8% from steam . generation capacity is approximately 55GW. A looming energy shortage requires soudi arabia to increase its capacity.capacity is planned to be increased to 120GW by 2032.

4) As voltage level increases cost of insulation also increases so it's not economical to use such high voltage level.And also as voltage level increases danger increases ,so considering the safety factor 230v/220v supply is used in our houses,so distribution voltage level is less.
