I am trying to understand the electronics theory behind why a high impedance, high resistance headset is needed for a crystal radio.
Obviously, a crystal radio can only produce extremely low voltage/current. A high resistance headset seems like it should need high voltage/current to overcome that high resistance. I realize this reasoning is wrong, but can someone explain to me why it is wrong. That's what is giving me trouble.
Thanks so much!
