The elements which may be considered for an ideal inductor as a solenoid,

(A) which is made of a thick wire
(B) which has negligible resistance
(C) which has a sufficiently large inductance
(D) which is made of a thin wire

Choose the correct answer from the options given below:

(A), (B) and (C) only

Explanation:

An ideal inductor is designed to have:

• A thick wire to minimize resistance and reduce energy loss.

• Negligible resistance so that it behaves purely inductively.

• Large inductance to effectively oppose changes in current and store magnetic energy efficiently.

Hence, (A), (B), and (C) are correct.
