NEET 2025 Physics: Wheatstone Bridge
Q. The current passing through the battery in the given circuit is:
1. 2.5 A
2. 1.5 A
3. 2.0 A
4. 0.5 A
Explanation:
It's a balanced Wheatstone bridge, so the central branch can be ignored.
Equivalent resistance: (4 × 8) / (4 + 8) = 32 / 12 = 8/3 Ω
Current = V / R = 5 / (8/3) = 0.5 A
It's a balanced Wheatstone bridge, so the central branch can be ignored.
Equivalent resistance: (4 × 8) / (4 + 8) = 32 / 12 = 8/3 Ω
Current = V / R = 5 / (8/3) = 0.5 A
This NEET Physics MCQ tests your understanding of Wheatstone bridges and current calculation. Recognizing a balanced bridge helps you simplify circuits faster, which is essential in NEET 2025 Physics questions on electricity.
