Hello I'm working on building a open energy monitoring system using a arduino uno and one or two of the 100 amps current clamp which can be found here. I have searched around online and found the website openenergymonitor.org and saw this which can get me started. But my problem is for the resistors. I have the 10k resistors and the 33ohms resistor it needs plus the 10uf capacitor. But most schamtics i saw is using 1/4w resistors. My 10k reisistors are 1/4w, However the 33ohms resistor is 1/2w. I don't know much about resistors. Just enough to get me by. But i was wondering if i would be okay to use that 1/4w 33ohms resistor sense it i the only one i have available?

You have my permission to try them. Do you need more permissions or do you need a consensus of all who read you post?

Aww Paul thank you for giving me your premission that way awesome of you. I'll be looking for a future premission slip from you saying it's alll okay.

I think it’s more like a teacher giving permission to a student to go to the bathroom.
Whatever happens on the way to the bathroom, in the bathroom, and coming back from the bathroom is all in the hands of the student.
If your project will work with a 1/4w 33ohm resistor, replacing that with. 100,000w
33ohm resistor will make no difference (except board size).
The maximum power dissipated by the resistor is determined by I^2R which equals 0.0825 watts. A 1/4 watt resistor is certainly adequate.
Hello Wattsthat. Thank you.
Think of resistor like a glass.
If you have one litre glass and want to put in a dash or a quarter litre or a half liter. All OK
IF you try to put in two Liters....
