Practical knowledge in electronics

[zahero_2007]

Hi guys , I don't know anything in electronics past how to calculate voltage and currents in circuits containing resistors and batteries . I lack the practical knowledge of how to construct real circuits . I want to know how to design real circuits . Can some one please point me to resources on how to design real circuits.a lot of websites are full of schematics but I do not know how to use those schematics to design circuits

Here are a few resources that might be useful:

http://www.wisewarthog.com/electronics/recommendations-practical-analog-electronics-books.html

The first in the list (allaboutcircuits) is a very easy introduction and you can download if for free. If you want to spend some money, take a look at "Practical Electronics for Inventors" by Scherz.

Start with the most basic thing. V=I*R

Voltage = Current X Resistance

This one single equation can carry you a long, long way...and it always holds true without exception.

Consider perhaps getting some schooling?

I think zahero knows about Ohm's law - he said he can calculate voltage and current for simple circuits. But I agree, the theoretical foundations are important.

There was a similar question not long ago.

See
sparkfun dot com
discovercircuits dot com
tinaja dot com
allaboutcircuits dot com

and search out hobby sites.

and be sure to get your basic quantities well understood

charge
current
potential
energy
work
power

When you can explain each in simple terms you are ready to start building things.
