Product description
- A coil wound on a non-magnetic cylindrical frame has N = 250 turns and inductance L1 = 36 mH. To increase the inductance of the coil to L2 = 100 mH, the coil winding was removed and replaced with a thinner wire winding so that the coil length remained the same. How many turns are there in the coil after rewinding?
