Electronic – Can someone double check the resistor identification

resistors

I have a resistor I need to replace. It is fairly large measuring 11mm long with 4mm diameter. All of the hobby resistors I have are 1/4 watt and make this thing look gigantic.

Do you think it is a 1 watt, or is there some larger value it could be?

I am also attempting to read the bands, and I see: Red Red Silver Gold. Which is a 0.22 Ohms 5%. Am I reading this correctly?

Resistor in question - .22ohm 1W?

I was actually able to find the schematic for this power supply, and it is a .22 Ohm.

  1. 0.22 ohm sounds right - it's hard to tell from the pic if the silver band is actually a blue one (glare), but my guess is you have it correct.
  2. Based on your size measurements, it could be either a half-watt or a one-watt. There are 2-watt and larger resistors but I don't think that's what you have.
