[Power Supply]

I want to be able to regulate the current (I really dont know how many amps I need) and have it go down to zero volts. The reason that I am looking to have a "plug in" regulator is so that I can still use the power supplys full Amps and Volts. I guss what I am trying to say is that I want to beable to plug in a regulator when I need lower Volts (less then 12volts) and Current (less then 7 amps) for the project that I might be working on.

[Power Supply]

I have a 13.8VDC, (adj. from 11VDC to 15.5VDC) 7 amp continous, 11A ics @ 50%duty cycle linear power supply.

What I want to do is to build a regulator with displays that will regulate the voltage and the current lower then the 15.5VDC max that it puts out. I want to beable to plug it in to the power supply so I dont have to tear it apart. Or should I just build a new regulator and gut the power supply and use the transformer and bridge (there is 24VDC from the bridge before it enters the regulator section?

The transformer has 4 leads coming out of it, a yellow and white coming out of each side. The yellow leads go to the bridge and the white go to the regulator section.

Thanks in advance......

Thanks for the Info especially the link. The info there has cleared up some questions that I have had

[Setting up a lab]

Hi all.... I am starting to set up my lab and need some info
What is a good assortment of resistors to have on hand?
What else is good to have on hand? ???

Thanks in advance.... ;D

[Math Book]

I am in a distance learing course for electronics. I am understanding the concept of Resistors, Pots, Rheostats, Resistive devices, and capacitors. Were I am having a hard time is the math. So what I need to know is there a electronics math book  for dummys?
Also another thing that I need is a lot of questions on the subjects that I can work out to beter understand the use of the formulas so I can answer questions like:

You plan to build a line-operated power supply for a battery-operated Sencore transistor tester that you bought at a garage sale. The tester is powered by a single 9V transistor battery, but is also has a coaxial jack on the side of the case for plugging in the power cord from a DC adapter. You figure you can build one cheaper than buying one of those DC adapters that plug into a wall outlet, plus you'll gain some experience. Which one of the following is an acceptable transformer secondary voltage, assuming you'll add just a single silicon diode rectifier and one cap for this project?

a.  5 volts

b.  6.3 volts

c.    10 volts

d.    12 volts


Is there any were on line that I can go to find the information? On line tests?

Any and all......

Thanks
