Two different electrical devices have the same power consumption, but one is meant to be operated on

Question:

Two different electrical devices have the same power consumption, but one is meant to be operated on 120-V AC and the other on 240-V AC.

(a) What is the ratio of their resistances?

(b) What is the ratio of their currents?

(c) Assuming its resistance is unaffected, by what factor will the power increase if a 120-V AC device is connected to 240-V AC?
