Answer: mutual inductance and self inductance of two coils.Self-Capacitance Effect: The effect of self-capacitance causes coil inductance to read lower than its true value, when measured on inexpensive inductance meters. Because multi-layer coils tend to have much higher self-capacitance than single layer coils, the difference between measured and true inductance can be expected to be greater.Coil Inductance Calculator To calculate the inductance of a single-layer, air-core coil: 1.
