Physics Electricity Research
Electricity has become the main sources of domestic energy in Australia over the last 200 years and played an important role in today’s society, industry .
In the early time when the British started to settle in Australia, firewood was the most important fuel.
In 1831, Michael Faraday put forward the electromagnetic induction, which led to the development of electric generators and made the large amount of electricity supply become possible. After 1879 when the perfect light globe was designed by Thomas Edison, electricity soon replaced gas for lightening. Following is the development of electricity in NSW.
1888 Tamworth the first town in New South Wales to have electric street lights: Young followed later in the year
1889 Street lighting in Penrith and Moss Vale
1890 Street lighting in Broken Hill
1891 Street lighting in Redfern
1892 Street lighting in Newcastle
1902 First electric street lights in the city of Sydney installed in King street between Elizabeth and Pitt streets
1904 First public power station built at Pyrmont with a total capacity of 1500 kilowatts
1905 519customers connected (Many customers) were unable to use electrical energy in their factories because of the cost of the motors. A scheme to hire motors was introduced and two years after its commencement 361 motors were on hire.)
1910 Decision made to change completely to electric public lighting in the city of Sydney.
1913 Almost 10000 customers, with total consumption of 40 000 000 units if electricity.
1914 Two submarine cables lay across the bed of Sydney Harbour to supply the northern side of the harbour.
In these days, different devices required different voltages, so that there were different specialised generator and separate lines. For example, street lights and trams required total different system. Generator had to be relatively close to the loads ( a mile or less for low voltage devices) because transmission was inefficient for low voltage and high current
