A 9-V Battery Is Hooked Up to Two Resistors in Series

question 55

Multiple Choice

A 9-V battery is hooked up to two resistors in series using wires of negligible resistance.One has a resistance of 5 Ω,and the other has a resistance of 10 Ω.Several locations along the circuit are marked with letters,as shown in the figure.Which statements about this circuit are true? (There could be more than one correct choice.)

• A)The current is exactly the same at points A, B, C, and D.
• B)The current at A is greater than the current at B, which is equal to the current at C, which is greater than the current at D.
• C)The current at A is greater than the current at B, which is greater than the current at C, which is greater than the current at D.
• D)The potential at B is equal to the potential at C.
• E)The potential at D is equal to the potential at C.
