voltage drop

Hello, I'm trying to design this simple power supply. The load voltage slightly drops or sags as I increase the load current. When the load current is 1 A (or above 1 A), the output becomes 9.3v which is too low to my application. What can I do to keep the load at about 11v even when the load...

Hi all and thanks in advance for your time ! I am currently designing an LED light sources that has 4 individual strings of LEDs, to be controlled by a commercial constant current machine vision driver (Smartek HPSC4). One of the strings has significantly less LEDs than the others (3 vs 8, 9...

My goal is to power 600 WS2812B RGB LEDs at full power. Currently, when all LEDs are set to white (255, 255, 255) at max brightness, a color gradient from white to red is displayed. I discovered that this also happens when, for all LEDs at max brightness, any one RGB channel is maxed out and...

Hi All, I have a issue I am trying to resolve. I am using a timed output relay (Redarc TIM05) as a kill switch. Once a momentary button is pushed, an output is set at 30 seconds, supplying 12v to pin 86 of a 30amp relay that runs inline with the starter motor trigger. The issue I am having, is...

Hello All, I have a wall adapter that outputs 24v AC and a small motor that requires 6v AC what resistor value is required for this voltage, please? Are resistors the same for AC as DC?

Hello Let me start by mentioning that I have little knowledge in this field. LEDs I have: 12v 1Meter Rigid Double-row 3pin LED strips with 1.8A total draw (0.9A each row). For some reason, they have massive voltage drop. With 12v input they measure 10.5v at the end of 1 meter and the lights...

Hello I'm a student and I have conducted an experiment where I buried a wire underground. Since there are many underground conductors in Seoul(where I live), I've always thought whether metal substances from the earth would effect the conductor's transmission. If the magnetic fields of the...

Please bear with me as I am a circuit-design newbie. I'm obviously misunderstanding something basic and will kick myself when you explain it to me. I have gotten the bug to do some electromechanical computing circuits using relays. I was warned that "that way lies madness" but like a fool I...
