A coil inductor has a length between 10-25 cm, and the coil should be 1 mm or 1.5 mm in diameter. To achieve an energy of 1.5 × 10⁻¹⁷ joules, what parameters should be selected?
Can you achieve a current of 0.000000000000002 A in a practical design of this inductor?
How can you decrease a current of 0.0000002 A based on these equations?
