First of all check your fuse box to make sure the fuse hasnt tripped if it has then flick it back up to test but if the fuse doesnt stay up & keeps tripping then theres a problem with either the pull cord switch that powers the shower up or a problem with the shower itself,Remember the electric to a shower is very dangerous the same as any electricity so take care & if in doubt call an electrician or plumber to have a look at it for you.
