74. Because the receiver would offer a large impedance to the high-frequency current, that is, seriously impede and so reduce the high-frequency current, we connect a condenser around the receiver.

And so it has, but we usually call it "impedance" instead of resistance because straight wires resist but coils or condensers impede alternating e.

The impedance of its secondary will be a quarter of this or 3,000 ohms.
