NEET PYQ Pattern Analysis (2018–2024)
| Year | Topic Tested | Type | Key Concept |
|---|---|---|---|
| NEET 2018 | Motional EMF | Numerical | ε = Bvl, force on rod F = BIl |
| NEET 2019 | Lenz's law | Conceptual | Direction of induced current |
| NEET 2019 | Pure inductor power | Conceptual | Wattless current, P = 0 |
| NEET 2020 | LCR circuit | Numerical | Z, φ, power factor |
| NEET 2021 | Resonance properties | Conceptual | Z = R at resonance (not zero) |
| NEET 2022 | Motional EMF, coil | Numerical | Faraday's law numerical |
| NEET 2023 | LCR properties | Conceptual | Phase angle, power factor |
| NEET 2024 | Transformer | Numerical | Turns ratio, current ratio, efficiency |
High-Frequency Concepts (appear almost every year)
- Resonance condition (Z = R, = ) — tested conceptually every 2 years
- Motional EMF (ε = Bvl) — numerical almost every year
- Transformer — numerical every 1–2 years
- Wattless current — conceptual every 2–3 years
Strategy
- For Lenz's law questions: draw the flux direction, then determine the direction of induced current by opposing it.
- For LCR questions: first compute and separately, then net reactance, then Z.
- For transformers: voltage ratio = turns ratio; current ratio = INVERSE of turns ratio.
