How is inductance affected by the guage of the coil?


I am trying to get 2.5mH .58ohms, how can I achieve that, there is a total of 780 microfarads in the circuit, with two 1n5402 diodes.

Here's a nice website to calculate coil inductance:

http://www.crystalradio.net/cal/indcal2.shtml

Inductance goes as the number of turns squared

The coil diameter is the next biggest effect

Wire gauge matters the least

Dirk Longstreet is back, and he's madder than ever. Longstreet (French action figure Olivier Gruner), a college professor who is a retired martial arts champion, is called into service when his girlfriend, the ambitious reporter Nicole Kent (softcore veteran Gail Harris), is caught by the corrupt guards of a corrupt prison run by a corrupt warden as she captures on video the corrupt kickboxing-to-the-death contests staged for the amusement of the prisoners. They let a very large prisoner, Pike (Jim Shagen), have his way with her (off camera, thankfully). As the now-comatose Nicole hangs onto life in a hospital, Longstreet, with the help of a newspaper reporter (Lorenzo Lamas) and his editor (Jalal Merhi), shaves his head and goes into the prison to bring the villains to their knees, and if he has to break them first, all the better. ~ Buzz McClain, Rovi

Peavey Valveking 112 : The Best of Modd 1/2

Please help me to find the answer. Title : DC alternator .?


1) Most aircraft alternator are 3 phase & their winding are connected in ............ connection .

2) If all the six DC alternator diodes open circuit , the effect of its output would be ....................

3) How many slip rings and brushes required for its field of the alternator?

Star,output would be zero,only 2 slip rings to feed rotor windings so only 2 brushes from voltage regulator.But what the hell is a DC alternator,all alternators are AC.Dynamos are DC and have a commutator and pick up brushes and a FADE box for voltage and current control.All alternators are 3 phase whether for aircraft,cars or power stations
