A resistor, R, is made out of a particular material with resistivity P. The cylindrically shaped resistor has length I and radius r. To get four times as much resistance in your resistor you could
  1.make the radius four times as big.
  2.make the radius half as big.
  3.make the radius one quarter the size.
  4.make the radius twice as big.

Question 2

The potential difference across a resistor R, and the current running through it, both increase. We know that resistance
  1.decreases.
  2.increases.
  3.remains the same.
  4.changes in ways we cannot determine with the information given.
