Question

A 9 V battery is hooked up to two resistors in series. One has a resistance of 5 ? and the other has a resistance of 10 ?. Several locations along the circuit are marked with letters, as shown in the figure. Which statement is true?

(Point A is located immediately after the battery at the + end. Point D is located immediately before the battery at the - end. Points B and C are resistors that are placed equidistant from one another and Points A and D) Sorry I couldn't provide the picture but if you type in the question to your database, you'll see a question just like it with the exact picture I'm talking about.



a. 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.

b. 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.

c. The current at A is equal to the current at B, which is equal to the current at C, which is equal to the current at D.

Explanation / Answer

c is the correct answer...in a series circuit, there is a single path for flow of current, and thus the current at each point is identical.
