An inductor coil of inductance L is divided into two equal parts and both parts are connected in parallel. The net inductance is
1). L
2). 2L
3). L/2
4). L/4
An inductor coil of inductance L is divided into two equal parts. Now, each inductor has an inductance of L/2.
Both these parts are connected in parallel.
