Reverse Search
Reverse Search allows you to search within the full text of dictionary entries for words, word parts, and phrases.
Search for entries that contain:
Exact matches of any of the individual words entered in the search box.
Example: Searching for "apple orange" identifies all entries that contain the word "apple" or the word "orange."
Any form of any of the individual words entered in the search box.
Example: Searching for "apple orange" identifies all entries that contain the word "apple" or "apples" or "orange" or "oranges."
Exact matches of all of the individual words entered in the search box.
Example: Searching for "apple orange" identifies all entries that contain the word "apple" and the word "orange."
The exact sequence of words and/or characters entered in the search box (for example, a fragment of a word, a single word, multiple words, or even a phrase containing punctuation)
Example: Searching for "a variety of apple" identifies all entries that contain that phrase. Searching for "app" identifies all entries that contain the letters "app," such as occurrences of "apple," "application," and "apply."

| AC1 |
abbreviation of "alternating current," electrical current that reverses direction at regular intervals. (Cf. "DC.") |
| commutate |
to reverse the direction of (alternating current) to create direct current. |
| converter |
an electrical device that converts alternating current into direct current or vice versa. [1/5 definitions] |
| diode |
a semiconductor used to convert alternating current to direct current; rectifier. [1/2 definitions] |
| dynamotor |
an electric machine that transforms direct current into alternating current. |
| impedance |
a measure of the total resistance of an electric circuit to an alternating current flow, usu. expressed in ohms. |
| induction coil |
a transformer for converting an interrupted low-voltage direct current to an intermittent high-voltage alternating current, as in some automotive ignitions. |
| inverter |
that which inverts or converts to an opposite, esp. an electric converter for transforming direct current into alternating current. |
| magnetic amplifier |
a tubeless amplifier that employs two sets of windings, a primary set into which input feeds and a secondary set through which flows an alternating current, whose variations are modified by those in the primary winding. |
| reactance |
in electronics, one of several measurable components of the total resistance in a circuit to the flow of alternating current. |
| rectifier |
an electrical device, such as a vacuum tube, that converts alternating current to direct current. [1/2 definitions] |
| thyristor |
