[Amps] dumb query about fuses (maybe!)

[Van K7VS]

I know ohms law so don't need the math.  Just a very specific question 
regarding fuses used in an amplifier on the AC side.

My amp requires 15 amp fuses if using 125V and requires 10 amp fuses for 
220V operation.

Does the voltage of the fuse make any difference??  i.e  What happens if I 
use a 15 amp fuse rated at 125V rather than what they ask for?  (10 amp at 
240V)....does the voltage rating make a difference??  Or just the current 
rating of the fuse?

And finally, is a ceramic better than a glass fuse for some reason?

I know this may sound pretty dumb to some but missed the the class on fuses.

Thanks much.  Van, K7VS
