Page 999 - The reduced cost of transmission by use of high voltages and transformers, greater simplicity of generators and motors. facility of transforming from one voltage to another (either higher or lower) for different purposes.
Page 997 - A current which reverses its direction in a periodic manner, rising from zero to maximum strength, returning to zero, and then going through similar variations in strength in the opposite direction; these changes comprise the cycle which is repeated with great rapidity.
