Higher the self-inductance of a coil_____________?
Correct answer: D. longer the delay in establishing steady current through it
- A. lesser its weber-turns
- B. lower the e.m.f. induced
- C. greater the flux produced by it
- D. longer the delay in establishing steady current through it
Explanation
In an RL circuit, the current time constant is τ = L/R, so a larger self-inductance makes the current take longer to reach its steady value. This is the delay caused by the coil opposing changes in current.
