Example 2 · difficulty 2/5
A pure inductor of self-inductance 0.1 H is connected across a 110 V (rms), 50 Hz AC supply. Neglecting the coil resistance, the rms current through the inductor is approximately:
- A. 3.5 A
- B. 7.0 A
- C. 1.75 A
- D. 35 A
Example 3 · difficulty 2/5
A 100 μF capacitor is connected to a 220 V (rms), 50 Hz AC source. The rms current flowing in the circuit is nearly:
- A. 3.45 A
- B. 13.8 A
- C. 0.69 A
- D. 6.9 A
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.
