Nettet11. feb. 2024 · Inductance is a measure of how much the inductor resists changes in its magnetic field. It can be altered by changing the number of loops in the coil, the gauge of the wire, and the material the core is made of. The SI unit for Inductance is the Henry (H). Applying this new definition of magnetic flux to Faraday's Law, we can derive an … NettetExample series R, L, and C circuit. Solving for Reactance The first step is to determine the reactance (in ohms) for the inductor and the capacitor. The next step is to express all resistances and reactances in a mathematically common form: impedance. (Figure below)
