Hi all, As a student in elctronic sciences, I'd like to know why there is a difference in the voltage required for PC boards with surface mounted devices and the voltage needed by traditionnal components like leaded film capacitors? I wonder if it

Capacitor working voltage One very important rating of capacitors is "working voltage". This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. This working voltage is expressed in terms of DC but th

Hi Everyone, I have a number of LED's of different voltages. Would someone please tell me how I can measure the voltage of each LED so I don't apply the wrong voltage and burn them out. Thanks. JW

So, what is 'high voltage'? anywho? * We sort of use 10 kV as the starting point for 'high voltage'. * National Electrical Code defines a much lower starting point (300 or 600 V?),

The issue is not the shoes, coats, straps, or doodangs. This issue is the voltage that the component / assembly 'sees'. * What voltages are you seeing in this work area? * What voltage will damage the components in this work area?

How many types of Voltage Power Supply Modules and how it is work please tell me in details. http://www.tekxplore.com/high-voltage-electronics/

It's always safer to use a higher voltage cap than a lower voltage cap. It isn't a fuse... There is only one case where we dropped the voltage on a cap. We were using a tantalum cap that was rated to 16V, but had been built in the standard packagi

What is happening is your bench supply is unable to supply enough current so the voltage drops. When you turn up the volume knob your asking for more current and the voltage drops more (the led's in the faceplate dim). It also sounds like when you

I think you are talking about Infra Red motion detectors.Most of them are 4.5V. You can use a voltage regulator 7805 IC(5VDC Output) after your 12 or 9VDC supply. In case your detector requires a different supply voltage simply choose a 78XX(XX=Volt
