How a transformer works, and how to design them. Dissection of a transformer. A transformer is a device in which two circuits are coupled by a magnetic field that is linked to both. There is no conductive connection between the circuits, which may be at arbitrary constant potentials. Only changes in one circuit affect the other.
Henley Royal Regatta. Henley Royal Regatta, annual four-day series of rowing races held the first week in July on the River Thames, at Henley-on-Thames, Oxfordshire, Eng. The regatta was established in 1839; and in 1851 Prince Albert became its patron and gave the event its âroyalâ prefix. The regulation distance for the races is 1 mile 550 yards (2,100 m).
The Enclosures Two main areas for race-(and people-)watching sit side by side on Henleyâs towpath. The Stewardsâ Enclosure is the Regattaâs first-class cabin, only accessible for 6,500 current members and their guests.Thereâs a 10-year waiting list for membership â good luck â and a stringent dress code applies (see below). Just downstream is the less formal Regatta Enclosure, which is open to the hoi polloi. JD Bishop, of the Leander Rowing Club, umpired Henleyâs first Regatta â on horseback. 2  If you think you see similar this year, itâs time to go home. 3  Beware Pimmsâ devilish cousin, the Royale. 4  At one part Pimms, 10 parts champagne, remember: Royale equals ruin.
