It is possible to use a rectified and smoothed mains input to power the LED bias circuit but the resulting supply voltage (VDC) will be much higher than the forward voltage (VF) across a single LED, meaning that considerable power would be wasted in the ballast resi...
Ok, so we have 3V and we want to have 15 mA going through the resistor and the LED. To find the necessary resistor value we useOhm’s law. this gives us So the necessary value for the current limiting resistor is 200 Ohms. Choosing the right resistor So you know that you need a 2...
Adding a current limiting resistor or fuse in series with each switch will help prevent this type of damage. 在每个开关上串联一个限流电阻或保险丝,将有助于防止这种类型的损坏。 www.eefocus.com 2. After the current limiting resistor in series and connected to the phase plug. 限流电阻串联后并连...
There is a 3-ohm resistor in-line to the LED array. I don't have any info about the model or forward voltage for the LED array, but if I'm increasing the supply amp capacity, can I assume proportionally I'd need about a 7-ohm resistor? Is a 2W resistor sufficient? The existing ...

PURPOSE:To obtain a current-limiting resistor having a high shortcircuit current- controlling effect, of small size, and of little normal voltage drop, by providing an oxide superconductor formed into a folded shape midway through an electric system line while maintaining said superconductor at a ...

but by providing a target voltage, the system will automatically calculate the necessary series resistor. If for example the LED is destined for 14 V, this device will not only show how the LED looks at the chosen current, but will calculate the required resistor to get the same results on...
