We know that fact because we know that an iron core increases the inductance and so chokes the current.
But what would happen if we should decrease the capacity and increase the inductance?
The signal had been transferred by inductance in the wall wiring and amplified over the public-address system.
The first is that the inductance will be larger if the turns are large circles.
Ive been over the antenna and the insulation, and Ive worked back to the inductance and the condensers.
Suppose you wind two inductance coils and connect them in series.
This means that the best conditions exist when the resistance is low and the inductance large.
We can either adjust the capacity as we just did, or we can adjust the inductance.
The cell will not, however, act as a break at all unless some inductance exists in the circuit.
We used a double metallic circuit so as to avoid the effects of inductance from our electric lighting circuit.
