I'm a little stuck... Click here to teach me more about this clue!

'dynamic' is the definition.

I can't explain the rest of the clue.

(Other definitions for electric that I've seen before include "Charged with sudden thrill" , "Full of expectation" , "Relic etc charged with current" , "startling effect" , "Highly charged" .)

I've seen this clue in the Evening Standard.
