Why would they put 6mA when you are suppose to send 2mA?
9v/6mA is 1500Ohms. If they added a 3k resistor in series with their setup, they would've up the total resistance to 4500Ohms, resulting in 9v/4500Ohms = 2mA of current.
To clarify, we measured about 8000 Ohms of resistance through the head, using our electrodes. For some reason, our measurement was off. I'm assuming it's a problem with the electrodes. To fix this issue, we'd need constant monitoring and adjustable resistance. In no way was I planning on running 6mA through my brain.
Hey, I'm curious how you plan to limit current issues through the electrode contact quality. I know when putting on EEG electrodes you can test the impedance, would something like that be needed here?
