| 11 | 13 | * When you connect a power source to one side of an inductor, the voltage immediately appears at the output. However when you start to draw current (electrons) through the inductor, a magnetic field builds around the inductor before electrons start flowing through to the output. If current continues to flow, the magnetic field will eventually saturate and electrons will then flow unimpeded through the inductor (i.e. at that point it looks and behaves just like a wire with no inductance). During the time the magnetic field is building, the inductor effectively **impedes** the increasing flow of current. |
