Ohm’s Law, Incandescent Filament, Voltage, Current

I read a forum post where the OU claimant and his correspondent agreed that the current would go up if voltage was reduced so that the bulb’s wattage would remain constant….. and of course this is nonsense. Only a profound misconception about Ohm’s Law and the quantities it defines and relates could result in such error. So I am prompted to correct the misconception….. for all the good it may do.
