Assuming a non-wimpy power supply, 100%.
That, and lots of other ways.

Usually testing has next steps:
1 move as far away from the electronics as possible
2 turn on the power
3 do you see the light (!) ? If so, the test failed, stop it.
4 wait a minute
5 do you se smoke ? If so, the test failed, stop it.
6 do you smell anything? If so, the test failed, stop it.
7 wait a minute, then touch the eletronics, espacially the power parts
8 did you burn your fingers? If so, the test failed, stop it.
9:
You reached the end of the test. Does it actually work? If so, keep
your mouth shut to the commercial people in your company and make all
neccesary improvements before they claim the project to be finished
and make a product from your first test setup.
