Hi

I need to check a 3kw x 27" immersion heater element to see if it's working.
If I connect my multi meter across the terminals, what resistance should I
find?

L-N around 20 ohms, but it may be less.
L-E should be o/c, if it conducts its electrically leaky and will pop
an RCD - but will work fine for a bit on a non-rcd supply, assuming a
decent earth connection. No decent earth and you'll really have a
problem.
