In case of an inductance, current is proportional to___________?
Correct answer: B. magnetic field
- A. voltage across the inductance
- B. magnetic field
- C. both A. and B.
- D. neither (A) nor (B)
Explanation
In a linear magnetic circuit, current is proportional to flux and hence to magnetic field strength, while voltage is proportional to the rate of change of current. Therefore, the magnetic-field option is appropriate, not voltage across the inductance.
