What reading level is Electricity book?
To quickly assess the difficulty of the text, read a short excerpt:
M. F. , or generally of any e. M. F. Induced by the motion of a conductor in a magnetic field, may be determined by using the right hand as an indicator. Put thumb, forefinger and middle finger again into mutual quadrature, and place the hand so that the forefinger 172 ELECTRICITY points along the lines of force and the thumb along the direction of motion, then the central finger will indicate the direction in which an e. M. F. Is induced. The power of the system represented by the moving wire ...may be ex- pressed either mechanically as the product of force and velocity, or electrically as the product of current and counter e. M. F. Both must be equal, since in nature power can neither be created nor destroyed ; it can only be transformed. By equating the two ex- pressions for the energy we obtain the relation between the mechanical and the electrical unit of power. Engineers measure power in a unit called the horsepower, electricians measure it in a unit called the watt, so named after James Watt, or the kilowatt, which means 1000 watts.
