A student builds the circuit shown above to demonstrate Kirchhoff’s Junction Rule (Conservation of Charge). The numbered points along the circuit indicate places where an ammeter could be inserted. Because there are two parallel branches in the circuit, there should be two smaller currents that sum to equal a single larger current.

Which of the following options gives a possible combination of three numbered points for ammeter insertion that will show the three distinct currents the student is trying to demonstrate?

A

Points 1, 3, and 5

B

Points 1, 5, and 7

C

Points 1, 2, and 8

D

Points 2, 4, and 8
