GraFxPro Posted September 10, 2005 Report Share Posted September 10, 2005 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 voltsb. 6.3 voltsc. 10 voltsd. 12 voltsIs there any were on line that I can go to find the information? On line tests?Any and all......Thanks Quote Link to comment Share on other sites More sharing options...
