Short answer is NO, you will not. Your potential and resistance are backwards. Meaning your body has a higher resistance via your skin then the object you could hit with an ESD. That you got right. BUT... your strap has a lower resistance than both your body and the object you’re touching. E.g. a PCB or memory etc.
Your strap will then carry the current to your floating ground, and not your object because electricity is lazy. And ESD is a kinetic action meaning the field is due to movement and not just there because it’s there.
BUT, just in case make sure you use these best practices:
- Make sure your wrist strap is tight on your wrist and correctly worn.
- Attach the alligator clip to another METAL only object. (Not plastic or wood)
- Before you touch whatever you’re concerned with zapping touch your computer case, or something else that is metal to release any static charge you might have. Then touch the object you want to grab.
- ALWAYS use the one hand rule when you can. (One hand rule is only use one hand to grab a part, and the other hand should not be touching anything else.)
So in review, higher the resistance the greater protection from ESD. Also remember your wrist strap offers the lowest resistance of anything you touch thus the ESD will drain to it.
Make sense? If not I got a link I can give you. Just remember, attach strap to wrist, then to metal on case (outside or at a ground post), touch the case or another metal object BEFORE you touch the item of concern, and you should be 99% fine and in the clear.
