Sample questions
You've seen the pattern — here are a few of the actual PYQs.
NDA2024
An electric circuit is given below. V1 = 1 V and Resistance R = 1000 ohm. The current through the resistance R is very close to 1 mA and the voltage across point A and B, V_AB = 1 V. Now the circuit is changed to: where value of V2 = 5 V. The internal resistances of both the batteries are 0.1 ohm. The current through the resistance R is about:
- A 1.0 mA
- B 1.2 mA
- C 3.0 mA ✓
- D 5.0 mA
✓ Correct answer: (C)
