A circuit has two identical resistors, each with resistance R, connected in series. They add to give an equivalent resistance of 2R. If any internal resistance is negligible, which of the following would increase the current in the circuit the most?
  1.add another resistor, R, in series
  2.take away one of the resistors
  3.add another resistor, R, in parallel to those already in series
  4.It depends on whether the resistance is greater or less than 1 .

Question 2

As more resistors are added in series, the equivalent resistance of the circuit approaches infinity. In contrast, as more resistors are added in parallel, the equivalent resistance
  1. approaches infinity.
  2. approaches zero.
  3. becomes zero.
  4. approaches 1 .
