What its class does to the tone

Low class is the biggest group. With no mark it gives a mid tone on a live syllable, and a dead syllable splits on vowel length. These three lines cover most of what you will meet, and they hold for ค exactly as they do for every other low-class letter.

live syllable, no mark mid tone นา naa Rice field
with mai ek falling tone ค่า khâa Value / fee
with mai tho high tone น้อย nói A little

The examples are whichever low-class word shows the rule most clearly. The full grid for all three classes is here.
