When a pair of identical resistors are connected in series, the a. power b. current c. voltage will be the same for each resistor. 1. a and b only 2. a only 3. b only 4. all of these 5. b and c only 6. none of these 7. a and c only 8. c only 0?

The correct answer is 4) All of these.

In fact, when the two identical resistor are connected in series, the current flowing through them is the same, I. 

The difference of voltage on each resistor is

but the two resistors have same resistance R and same current I, so the difference of voltage on them is the same.

Similarly, the power dissipated on each resistance is

And again, the current I is the same for the two resistors, and they have the same resistance R as well, so the power dissipated is the same for the two resistors.
