You got 20 buckets in order from 1 to 20. Each bucket is numbered. (As follows: bucket #1, bucket #2, etc)
All 20 buckets have the same amount of coins.

19 buckets have coins that weight 1 gram each.
1 bucket have coins that weight 2 grams each.

The 1 gram and the 2 gram coins, look exactly the same.

You got an electronic scale with 1 gram resolution and just one chance to weight.

I which bucket (numbered from 1 to 20) are the 2 gram coins?

Did Mrs. Columbo actually ever had an appearance?

No, that's one of the running gags.
According to one website "Detective Columbo would often talk about his wife but she never actually turned up in the movies. In 1979, NBC decided to start a mystery show starring Kate Mulgrew. In an attempt to grab some of Columbo's audience, they made Kate Mulgrew's character, who was also named Kate, Columbo's long unseen wife. They called the show Mrs. Columbo and then changed it to Kate Columbo. Apparently the tie in didn't work because next the Columbo angle was ditched altogether. Kate became Kate Callahan and the show became Kate The Detective and then Kate Loves A Mystery. Then it became cancelled. "
