Example 2 · difficulty 4/5
A series LCR circuit contains an inductor of 8 H and a capacitor of 0.5 μF. The angular frequency of the source at which the circuit resonates is:
- A. 1000 rad s⁻¹
- B. 250 rad s⁻¹
- C. 500 rad s⁻¹
- D. 125 rad s⁻¹
Example 3 · difficulty 3/5
An ideal AC circuit consists of a source connected to a pure capacitor alone. The average power delivered by the source over one complete cycle is:
- A. zero, because the current leads the voltage by π/2 so cos φ = 0
- B. equal to Vrms × Irms, since the capacitor continuously stores energy
- C. equal to Vrms × Irms / 2, as the average of sin squared over a cycle is one-half
- D. non-zero and directly proportional to the capacitance C
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2017 Physics Alternating Current PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2017 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
