Question Siemens Q120 (single pole) breaker

maybe the easiest question ever asked here. I have a lighting panel with three Q120 20A breakers. the top two go to two lighting circuits, the bottom one to an outlet. The lights aren't working, and, when I measure the output of the two lighting breakers, I get 47Volts. Continuity through the closed breaker on the bench is almost one ohm. The third breaker output is 120V.

I suppose the easiest thing to do is to get a new $5 breaker from HDepot and see what the output is when installed, but I'm curious about the 47V. What am I ignorant of, or not understanding?

Welcome to the forums!

Are the two lighting breakers on the same bus? can you post a picture of your panel with the cover off?
