There's bound to be a charge for this current treatment (5,7)

Ross

I believe the answer is:

shock therapy

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

'treatment' is the definition.
(I know that shock therapy is a type of therapy)

'there's bound to be a charge for this current' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'charge' could be 'hock' (hocking is a kind of charging) and 'hock' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?

I've seen this clue in The Irish News.
