If all 3 resistors in a series 12V circuit are the same, what will the voltage be across resistor no. 3?

4V across each resistor, since they are equal and the sum must be 12 V.

Thanks, that's what I thought. Did you happen to see Part 2 of this question? It is: If the current at one corner of the 12V series circuit is 1.0 A, what is the current at corner number three (all three resistors are the same).
