COILS
The coils are circuit elements consisting of non-insulated conductive wires wound on an insulating material. The unit of measurement of the coil is Henry and is indicated by the letter H, indicated by L in the circuit diagrams and formulas. Henry is a great value, the circuits generally use coils of mH (miliHenry) and uH (microHenry). inductors generate magnetic fields and resist changes in current. Coils generally; It is used in power circuits, filter circuits or high frequency circuits.
