| An _____ stores a charge as a magnetic field surrounding the conductor. | inductor |
| If the strength of current flowing in a conductor changes, the strength of the magnetic field also changes. When a change in current occurs, the magnetic field generates a voltage in the conductor that's called ______________. | self induced electromotive force (self induced EMF) |
| Inductors are rated using the unit of measure called the _____. | henry (H) |
| High-frequency air-, plastic-, or ceramic-core inductors have little inductance and are rated in ______ or ______. | millihenries, microhenries |
| The 3 factors that can influence the inductance value of a coil are: the number of ____ in a coil, the _____ of the coil, and the _____ that the coil is made of. | turns, shape, material |
| To find the total inductance of two or more inductors connected in _____, add all the values of the inductors together. | series |
| A resistor can be connected in series with an inductor to create a __________ circuit (___ circuit). | resistance-inductance, RL |
| When voltage is applied to an RL circuit, the current flow won't reach its max. value immediately. This is because the inductor tends to oppose a change in current flow in a circuit. Instead, the current will build up over time until it reaches its ________ value. | steady state |
| Inductors are widely used as _____ components in industrial DC power supplies. | filtering |
| A high-frequency inductor can be made by placing a _____ bead over a straight conductor. | ferrite |
| A ______ inductor is used in a DC or low-frequency circuit. | iron core |
