Bad capacitors : How to spot them

Bad capacitors : 

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.

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.
