Marie is constructing a circuit board and observes that her current increases as she adds resistors. What statement explains why the current increases?
A) She is constructing a series circuit board so adding resistors draws more current.
B) She is constructing a parallel circuit and adding resistors increases the voltage.
C) She is constructing a series circuit so increasing the resistance also increases voltage and current.
D) She is constructing a parallel circuit board and the added resistors create more paths for the current, decreasing total resistance.
