OK.

Now, let me know this one.

The maximum rating of the multimeter for ampere testing is 10 ampere.

So, I guess my lamp did not exceed the maximum rating.
my lamp ratings are 12v/5w

OK, let me know if my multimeter for ampere testing usage is correct.

Thanks

I think you got it! Use I = P/E and see if there's a correlation.

The current for the lamp is 0.42 Amps.

Check Tony Kuphaltd's book for Multimeter use:

DC, Chapter 3, section 3.9 > "Safe meter usage", it's great!!

And don't get confused if the resistance of the lamp makes no sense: You have to measure that when the lamp is HOT and ON, so just infer it from the voltage across and that current your measuring thru it.
