P(watt)=I*I*RSo you need 50V on the 10k resistor to dissipate 1/4 watt on it..
I am using a 10k resistor to "pull_down" ground as the sensor needs stabilityI have a 10k connected now but its 1/4 wattis 1/2w better in case it gets hot ?
On a pulldown...?
Pull downs are not normal, are you doing things right?I dunno, it is working for the situation I needHere's the story:I have the 10k resistor connected to ANALOG INPUT and ground because of a floating input, when the sensor open circuits, ie: INPUT goes LOWThanks for the link, I tried both pullup & pulldown, both work fineThey say pullup circuits uses less current traditionally but does my hardware need pullup or will pulldown work OK too ?Just not sure why I would need, to use pullup if that's the case
