de-n-ki, three beats — the nasal in the middle is a full beat and comes out as "ng."
denki
Three beats, one of them vowel-less. It shares its shape exactly with 天気 (tenki) — same nasal, same ending, same three counts — so drilling the pair together makes both rhythms stick and highlights that only the first consonant differs.

電気をつけてください uses つけて, opening on a genuine affricate, and stacks it before ください. So after a nasal beat, the sentence asks for a つ produced as one release and then four more even morae with nothing held.
"DEN-kee" delivers two syllables with the n as a closing consonant and a lengthened final vowel. Hum the ん as its own beat, make it the velar variety, and halve the i. The e also drifts toward "day" in English mouths — anchor the tongue for its whole duration.
