Electronic Components


There are thousands and thousands of different electrical components, luckily they can be grouped together into parts that have similar functions. In this section we will go through these functions. These components manipulate electricity by moving, reducing, increasing, blocking, storing, switching and changing it. This is done with different types of matter, mechanical actions and chemicals.

This section contains:
  • Cables and wire - Moving electricity.
  • Switches - Turning off and on electricity.
  • Relays - Electrically controlled switches.
  • Audio Components - speaker and Microphones.
  • Resistors - Reducing electricity.
  • Capacitors - Storing electricity.
  • Coils - Building a magnetic Field.
  • Transformers - Change voltages.

[QUOTE\]Hello,

I'm just starting out and it seems like a pain to buy these tiny things as they are needed, can anyone recommed what a beginners should stock up on at the start?

thanks

Junk is the best to stock things like
old TVs have flyback coils caps, transistors and resistors maybe some rotary pots etc. radios often have coils and tuning cans, computers usually have a button cell battery holder and some really nice heat sinks and fans and a useful power supply, computer monitors often have wonderful components like 555 timers and other useful things, flat screens have inverter boards to power neon lights and magnifiers etc, the list goes on all these things contain a vast range of components if you have the patience to remove the components you need form them or have the storage space for them.

Energy Efficiency is very very important..
so pls use the resource in a proper way

Another noob question.

My LCD TV just went all smokey on me - taking out the power supply, I found a crispy capacitor. There are allegedly 2 identical CAPs on the high voltage side of the transformer and the only text I can see on the good one (the bad one being crispy to the point of crumbling) "27J 6KV"

Is this a 2uF (+-5%) 6000V capacitor? If so, anyone know where I can get such a beast in the UK?

Thanks for your time and trouble,

capacitor is descharging in time ... or if you want a quick descharging just make a short to the ground

"in vein"?! typos and illiteracy aren't the same thing.

where's your Op Amps section anyway?

Recently, I hard to search the Panasonic Solar Panel but in vein.
Thank you.
