Resistors B and C are equal. What is the current through resistor C?
- 4.5A
- 18A
- 9A
Explanation from PART66Online
The 9 A supply current flows through A and D and then divides between B and C, which are in parallel. Because B and C are equal, the current divides equally: 9 / 2 = 4.5 A through each. The 2 V and 6 V readings are not needed to find this current. The 9 A option is the total current before it divides; 18 A doubles it instead of halving it.

The question is incomplete! To know the current through C there should be a detail provided about B. Now, with assumption that C=B, note that the same 9Amps main current will flow up to the dividing junction of C and B. Since the resistive values of C ad B are equal, the 9Amps will equally divide between them. Hence the current through C will be 4.5 Amps.
