MHT CET 2024 Physics question
An inductor coil of inductance L is divided into two parts and both parts are connected in parallel. The net inductance is
Answer: (4)
Solution
The inductance of a coil of given cross-section is proportional to the number of turns, i.e. to its length. Dividing the coil into two equal parts, each part has inductance . Connecting them in parallel (mutual inductance neglected): $ =
