He added a margin of 50% arriving at 33,000 ft-lbs. Interestingly, Watt measured the rate of work exerted by a horse drawing rubbish up an old mine shaft and found it amounted to about 22,000 ft-lbs per minute. Watt strongly believed that the steam engine would one day replace animal power, where the number of horses replaced seemed an obvious way to measure the charge for performance. In 1757, James Watt, an instrument maker by trade, set up a repair shop in Glasgow in 1757. In 1733, Charles Francois du Fay discovered that electricity comes in two forms which he called resinous(-) and vitreous(+) which were later renamed negative and positive. In 1729, Stephen Gray showed that electricity doesn’t have to be made by rubbing and that it can also be transferred from place to place with conducting wires and this gave a new dimension to the idea of electricity. It’s association with the Greek word ”ẽlecktron” - meaning “amber” subsequently gave rise to the English words “electric” and “electricity” which first made their presence in print in 1646. We will add a detailed product description. His work led him to coin a new latin word - “electricus” - meaning “like amber”. Need more information Simply enter your email address below, and click OK. His thinking was later proved to be incorrect, because the magnetic effect that he envisioned was in fact “static electricity” as we know it today.Ĭuriosity into electricity remained more or less dormant until 1600, when English physician William Gilbert made a careful study of electricity and magnetism and discovered that the earth is in fact a giant magnet and explained how compasses work. Thales believed that friction rendered the amber rod magnetic in contrast to materials such as Magnetite which needed no rubbing. ![]() Thales of Miletus discovered, that when an amber rod was rubbed against cloth or cat’s fur, lightweight objects such as feathers and pieces of paper etc. The first discoveries of electricity were made back in ancient Greece in 600 BC. Ancient Egyptian texts dating back to 2750 BC refer to the effect of electric shocks delivered by catfish and torpedo rays and were aware that such shocks could travel along conducting objects. Electricity has fascinated human kind since our ancestors first witnessed the dramatic effects of lightning.
