Answer to Question 1

ANS: B
The relationships among current, voltage, and resistance can be explained with Ohm's law: V = I  R.

Answer to Question 2

ANS: D
Given the fact that when resistance is constant, there is a direct relationship between voltage and current; when voltage is constant, there is an indirect or inverse relationship between current and resistance. Therefore, if current is increased, resistance would have to decrease proportionately.
