The diameter of wire A is greater than the diameter of wire B, but their lengths and resistivities are identical. For a given voltage difference across the ends, what is the relationship between PA and PB, the dissipated power for wires A and B, respectively?
  1. PA = PB
  2. PA < PB
  3. PA > PB

Question 2

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor dissipates more power?
  1.Resistor A does.
  2.Resistor B does.
  3.More information is needed.
