If strobe is 1/2000 and sync speed is 1/250, how it works with longer shutter speed?

Greetings,

This is a rookie question. Given when using the non-high speed external strobe flash units, why are we not getting underexposed photography given the shutter speed is opened much longer than the length of time the flash is actually on (leaving most of remaining length of the shutter still opened in darkness)?

Thanks for any insight into how it works.

Because of the intensity of the flash output. Put simply, the flash generates a whooooooole lotta light in a very short burst.

Fish answered your question. However, I'm here to address the question you will think about down the road. What creatively can I do with the rest of that shutter time. You can slow the shutter even more and for example have someone run at you with a sparkler sparkling. Then set the sync on the camera to a rear sync and it will fire the flash at the end of the shutter and you will have a sparkler trail with a lit up subject at the end of the exposure. This was just meant to give you an idea. Get creative.
