Tramp catches current inside, and energy (7)

I believe the answer is:

traipse

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

'tramp' is the definition.
(I've seen this in another clue)

'catches current inside and energy' is the wordplay.
I cannot really see how this works, but
'current' could be 'i' (physics symbol) and 'i' is located in the answer.
'catches' could be 'traps' (trapping is a kind of catching) and 'traps' is present in the leftover letters.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?
