I’m an electrician learning refrigeration. Today I dug around an hvac heat pump unit. I found on the capacitor that I tested a single terminal that measured 300vac to ground. It is a 220v compressor motor.

My question is:
From a theory and logic standpoint how does the 220v go through the capacitor and motor and then read as 300v
