I was reading the specs on a photo eye and it states its current consumption
65 mA at 24v
120 mA at 12v
both situations end up with roughly 1.56 VA of power...how does it draw more current with less voltage applied. If V=IR, the only way i see it is the resistance of the system must lower in order to draw more current to maintain similar power. How does the resistance lower?
