An inductance of 1 H is realized using air core with 100 turns. What will be the inductance if the number of turns are doubled?
- A. 1 H
- B. 0.5 H
- C. 2 H
- D. None of these
Answer: D. None of these
Explanation: $L=\frac{\mu_{0}kN^{2}A}{l}$ if the number of turns is doubled then inductance becomes four times. Hence, new inductance $= 4~H$.
