 Watt Is An Amp?
 Frequently Asked Question:
What is a watt? What is an amp? And why is it important for me to know how many watts or amps my equipments draws? This is a very good and much asked question. It's important to know how much electricity your equipment consumes, because all sources of power are finite. Whether you're connected to a battery, a standard AC wall outlet, or the power pole outside your theater, there's a limit to the quantity of power available (albeit a pretty BIG limit, when it comes to the pole's power line :-) This answers the last

How to spot them

A bad capacitor or one that is starting to bulge will start to swell at the top, no longer looking indented

Others swell to the point of blowing thus you can see electrolyte brown crud on the top of the capacitors.

Why 95% P.C.B.s are of green colour?

Why 95% P.C.B.s are of green colour?

Answer: If the PCB itself is green, that indicates, that its made from glass-epoxy which is naturally green. Also your PCB could be made in every single color that exist. The finishing color is usually a solder mask. This mask is applied for safety reasons, for preventing eventual short circuits and etc. It could be every color, depends on the client's specifications.

What is Resistor

From Wikipedia, the free encyclopedia
Resistor
Resistor.jpg
A typical axial-lead resistor
Type Passive
Working principle Electric resistance
Electronic symbol
IEC-style resistor symbol


Axial-lead resistors on tape. The tape is removed during assembly before the leads are formed and the part is inserted into the board. In automated assembly the leads are cut and formed.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
