Read the passage below and choose the right answer to the following question (choices are reduced or increased ): We also saw that adding resistors to a series circuit increases the total resistance of the circuit, causing the current to decrease. Jim loves to build circuits. One day he builds a circuit that has less resistors then any other circuit he has built. Since the circuit has less resistors the amount of current in the circuit is reduced or increased?
increased
