Hi, I was studying Roentgen (and Crookes tubes) and realized that they used spark gap generators which sent out bursts of AC current. However, Crookes tubes work with one end being the cathode and one the anode. They did this before diodes so how did they ensure that one side was negative and one positive? Or is a Crookes tube *itself* a diode (meaning does it only work if one end is positive and the other negative)?
Any thoughts? Thanks, Kathy
