Yes, you could use an inductive ammeter/current clamp.
But you can't just clamp over a regular AC flex cord - since the active
and neutral would both pass thru the clamp.  Bit of a hassle to make a
separate cable that breaks out the active and neutral for regular home
use.

For use around the house it is probably easier to just buy a power/watt
meter.

I didn't realise they were so cheap these days...  I just ordered the
Sanwa Supply 'Watt Meter" TAP-TST8

I blame you Stephen J. Turnbull for that 1-click(R)(tm) impulse purchase!
