Two circuits have identical voltage sources. the only other elements in the circuits are resistors. the resistor in circuit a has a resistance that is four times as large as the resistance of the resistor in circuit b (ra = 4rb ). which statement below best describes the current flowing through the two circuits? (ohm's law: v = ir) a. the current flowing through circuit a is as large as the current flowing through circuit b. b. the current flowing through circuit a is 2 times as large as the current flowing through circuit b. c. the current flowing through circuit a is 4 times as large as the current flowing through circuit b. d. the current flowing through circuit a is as large as the current flowing through circuit b.
