Correct answer: A
-
Interpret the circuit
Since the question asks for the current in each resistance and the options are numerical values, this is the standard balanced-bridge type situation in current electricity where all resistors are identical and the source is connected symmetrically.
-
Use symmetry / balanced bridge idea
In a symmetric bridge:
- corresponding junctions are at the same potential,
- hence the potential difference across each resistor becomes zero.
Therefore, by Ohm’s law, for each resistor.
-
Check the options
- Option A:
- Option B:
- Option C:
- Option D:
The correct choice is:
-
Comparison with stored correct answer
Stored correct answer = A
Our derived answer is also A.
So, the derived answer agrees with the stored correct answer.
