MCQ
In the circuit shown here, at which point is the current least?
- AP
- BQ
- CR
- DS
✓
Answer
- Q
Explanation:
Current flowing through S is the combined current from Q and R.
Current flowing through S is the same as the current from through P.
Current follows the path of least resistance.
Hence more current would flow through the 4ohm resistor.
