Comfort today is using your five mega pixel, five time’s optical zoom to get that perfect shot. Knowing little one will have a movie of them blowing out candles on birthday cake with movie mode of new digital camera and being able to quickly see movie on 2 inch LCD size screen.
In past, a camera limited us in many ways, but today a digital still camera, with brands like Nikon, Canon, Sony and others, who have embraced new technology, a digital still camera has become an exciting instrument for all to photograph with.
Enjoy your pictures!

Testing Capacitor-How to test a capacitor when breakdown under load.Written by Jestine Yong
Continued from page 1
This proved that bad capacitor breakdown when under full operating voltage. Then, how do i confirm that this filter capacitor is faulty? By using an analog insulation tester. When i connect faulty cap to meter and press go button-it showed a very low resistance and this is proved of short circuit between plate when voltage applied! There is nothing to do with bad electrolyte. A good capacitor will just showed a charge and discharge in insulation meter just like you are checking a capacitor using analog multimeter. In market there is quite a number of ranges that you can buy. It has range of 50v, 100v, 250v, 500v, 1000v and even 5000v! If you want to test a capacitor of 100 microfarad 160v then you have to select 100v. If you select 250v, it will blow your capacitor that is under test.
If you have SENCORE TEST EQUIPMENT such as sencore lc meter LC102 OR LC103, these meters have capabilities of checking any type of capacitors with four test; -testing for capacitor values -checking for leakage -equivalent series resistance (ESR) and -Dielectric absorption It can check aluminum electrolytic capacitor, film capacitor, ceramic, high voltage capacitor and etc.
Conclusion-Different capacitor manufacturer produced different type of quality of a capacitor. Perhaps bad capacitor that i encountered are from lowest grade one. A capacitor failure when under load is very rare. Using ESR capacitor meter alone can solve most of electrolytic capacitor problem.
