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

question 38

Multiple Choice

A 9-V battery is hooked up to two resistors in series using wires of negligible resistance. One has a resistance of $5 \Omega$ , and the other has a resistance of $10 \Omega$ . 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 potential at \(B\) is equal to the potential at \(C\).
• C) 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.
• D) The potential at \(D\) is equal to the potential at \(C\).
• E) The current at \(\mathrm { A }\) is greater than the current at \(\mathrm { B }\), which is greater than the current at \(\mathrm { C }\), which is greater than the current at \(D\).
