When 4 V of potential difference is applied across Resistor A, 2 A of current flows through it. When 4 V of potential difference is applied across Resistor B, 1 A of current flows through it. When 12 V is applied across Resistor A, 6 A flows through it, and when 12 V is applied across Resistor B, 3 A flows through it. Which of the following is consistent with this data?
  1.Both resistors are not ohmic.
  2.Resistor A is ohmic but Resistor B is not.
  3.Resistor A is not ohmic but Resistor B is.
  4.Both resistors are ohmic.

Question 2

Doubling the potential difference across a length of copper wire causes what change to the drift speed of the charge carriers?
  1.No change occurs since drift speed is constant for copper.
  2.The drift speed halves.
  3.The drift speed doubles.
  4.The drift speed quadruples.

In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
