is, offers a much less impedance to a high jfrequency than to a low one, it was thought that the proper adjustment of capacity and inductance would separate the two currents ofdifferent frequencies.EXPERIMENTS- The first experiments were conducted for the .purpose offinding how small a condenser… … S is a rheostat, C a small condenser consisting of twosheets of tin 14 inches square, separated by a piece of ordinarybond paper, R the reciever, T the transmitter and G is an alter-nator giving 110 volts at 60 frequency.lt was found that the con-denser had a capacity great enough to make talking…
