What reading level is The Principles Underlying Radio Communication book?
To quickly assess the difficulty of the text, read a short excerpt:
It should be particularly noted that while the electrons move from the heated filament to the cold third wire, the" current passes from the third wire to the filament, according to the usual idea that the direction of an electric current is from the positive (higher) to the negative (lower) voltage. This dis- tinction between the direction of electron floiu and the direction of current floio should be carefully noted.
As each electron leaves the filament, the filament acquires a charge of posit...ive electricity equal in amount to the nega- tive charge carried by the electron. If no voltage is applied to the third wire, electrons will still be emitted by the incan- descent filament, but will travel only a very short distance before being attracted back to the filament by the positive charge acquired by the filament. The voltage applied to the third wire must be sufficient to overcome this attraction of the filament. No current will flow if the negative terminal of the battery is connected to the third wire, because the electrons will not be attracted by the negatively charged third wire, and, in fact, will be repelled back into the filament.
