Charging by Induction. The previous section of Lesson 2 discussed the process of charging an object by friction or rubbing. Friction charging is a very common method of charging an object.

Even though William Christopher W. C. Handy is called the Father of the Blues, the real origin of the blues is shrouded in mystery.
Chicago's blues style was not only faster and more turbulent than the Southern styles: it also adopted the horns and the electric guitar. Eventually, a new term was coined for this aggressive kind of blues music: rhythm'n'blues. Its birth date is disputed. In 1946 Muddy Waters cut the first records of Chicago's electric blues. In 1947 Billboard's writer Jerry Wexler coined the term rhythm and blues for Chicago's electric blues. In 1949 the Billboard chart for race records was renamed rhythm and blues. The first major rhythm'n'blues festival was held in Los Angeles in 1950 (the Blues & Rhythm Jubilee), as important as the Carnegie Hall concert of 1938 that launched boogie woogie nationwide.
