Practical knowledge in electronics

Click For Summary

Discussion Overview

The discussion revolves around the challenges faced by individuals seeking to gain practical knowledge in electronics, particularly in designing and constructing real circuits. Participants share resources and foundational concepts to aid in understanding and applying electronic principles.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses a lack of practical knowledge in electronics beyond basic calculations involving voltage and current in circuits with resistors and batteries, seeking guidance on circuit design.
  • Another participant provides a list of resources, including a free introductory book and a recommended paid book, to help with learning practical electronics.
  • A repeated emphasis on the importance of understanding Ohm's Law (V=I*R) is noted, with one participant suggesting that this foundational equation is crucial for further learning.
  • Some participants suggest that a solid grasp of basic electrical quantities such as charge, current, potential, energy, work, and power is necessary before starting to build circuits.
  • References to various websites and hobbyist resources are shared as potential avenues for further exploration in electronics.

Areas of Agreement / Disagreement

There is a general agreement on the importance of foundational knowledge in electronics, particularly regarding Ohm's Law and basic electrical concepts. However, the discussion does not resolve how best to transition from theoretical knowledge to practical application, as participants offer differing resources and approaches.

Contextual Notes

Some participants highlight the need for a deeper understanding of theoretical concepts before practical application, but the specific methods for achieving this understanding remain varied and unresolved.

Who May Find This Useful

Individuals interested in learning practical electronics, particularly beginners looking for resources and foundational knowledge in circuit design and construction.

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

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.
