Self-inductance of a coil is defined from flux linkage lambda and current I by?

  • AL = lambda/I for a linear magnetic system
  • BL = I/lambda
  • CL = lambda I²
  • DL = I²/lambda
Report an error
Correct Answer: A. L = lambda/I for a linear magnetic system
Explanation: For a linear magnetic system, flux linkage λ=LI, so L=λ/I.
Reference: Standard electromagnetic theory: inductance
