Hi guys, I'm looking to put a 16v 50mA current through to electrodes. Is there something I can purchase online that isn't too expensive (I'm based in the UK)?

I don't think you can buy a 50 ma current source in a retail store but you can buy a wall wart rated for 16 volts DC (or more) and add a resistor.
