Hi all,

I am new to all this DIY circuit repairing, soldering and stuff. Recently I broke this energy meter (PZEM-002 v2.0) of mine due to bad connections. There may be other faults too but at least this big sized resistor (pics attached) is burned out (confirmed using a multimeter). I have pulled it out and would like to replace it myself and see if that makes the board work. But I am finding it difficult to identify the exact value and type of this resistor. Seems to be 100 Ohm but I will really appreciate if someone can confirm it for me. Also is it of any special type?

If its indeed a 100 Ohm resistor then can I replace it with a "100 Ohm (Ω) 5 Watt Fusible Ceramic Cement" resistor. I have attached its pic too. I have also attached picture of this other board PZEM-004T (from Google) which is little different from my board but the resistor on it seems to be same.

Thanks,
Ron

 

You can this 5 band resistor color code calculator https://circuitdigest.com/calculators/5-band-resistor-color-code-calculator

 

Or use the one on this site Resistor Color Code Calculator and Chart—4 Band, 5 Band, or 6 Band Resistors - Engineering Calculators & Tools (allaboutcircuits.com)

I'd try and help you but I am colorblind...

 

100 ohms, 5% probably 3W.
