What reading level is How to Make Inventions Or Inventing As a Science And An Art a Practical Guide book?
To quickly assess the difficulty of the text, read a short excerpt:
A diaphragm-, pressing upon parallel carbonized silk or linen threads, is thrown into vibration by a vibratory current. The parallel currents in the filaments variably attract or repel one another.
Of two pieces of selenium included in an electric circuit, that one which is annealed is the more sensitive to light for the purpose of increasing its electrical conductivity by the action of light.
117 Sparking may be partially eliminated by providing an electric condenser or choking magnet of high ...self-induction in a shunt around the terminals at which the sparking tends to occur. A choking magnet is a long coil of fine wire upon an iron core. The magnet may have a closed secondary coil wound upon it.
Variation of a beam of heat upon a thermopile does not produce immediate and proportional variation of current on account of sluggishness of heat; but variation of a beam of light upon selenium in an electric circuit produces immediate and proportional variation of current.
A musical note, or at least a humming, is produced at the arc of an alternating current lamp; being produced by the rapid extinction and re-establishment of the current, the effect being similar to that of "singing flames.
