What is mean by the AC coil split?

AC coil split is a method for reducing the inductance of an AC coil. It involves cutting the coil into two or more sections and connecting them in series or parallel. This can be done to reduce the reactance of the coil, which can improve the efficiency of an AC circuit.

For example, if a coil has an inductance of 100 mH, cutting it in half and connecting the two sections in series would result in a coil with an inductance of 50 mH. This would reduce the reactance of the coil by half, which would allow more current to flow through the circuit.

AC coil splitting can also be used to change the inductance of a coil without changing its physical dimensions. This can be done by connecting additional sections of wire in parallel with the coil, or by using a combination of series and parallel connections.
