If must be apparent to anyone who has tried to read or study by the light of an incandescent lamp that there is occasionally such a great change in the impressed voltage as to be decidedly objectionable. These changes may be due to a turning on or off of a great number of lamps at the same instant, or to the closing or opening of a circuit containing a relatively big power consuming agent.
