6. Question refers to the following figure:
If R1 were to burn out, the current coming out from the battery would
- A. increase
- B. decrease
- C. stay the same
- D. There is no current, because the circuit is now incomplete.
Correct Answer: B
If R1 were to burn out, the total resistance in the circuit would increase. Because I = V/R, this increase in resistance would decrease the current.
