Nettet31. des. 2015 · The LED's datasheet (or an educated guess) tells you what current the LED needs to work. To much & it burns out, too little and it's too dim to see. So calculate the available voltage (power supply voltage - forward voltage). Divide this by the current you want to run the LED at, to get the resistance.

Thus, limiting the current … Nettet18. mar. 2024 · jremington March 17, 2024, 2:16am 2. A resistor is required to limit the current through each LED, except in the case that LEDs are in series. The parallel connection you are describing will not work because individual LEDs have slightly different characteristics. That means that the current through the resistor would not be divided … NettetThe failure of a bleeder resistor prevents the discharge of the capacitors, resulting in dangerous voltages being retained for many days. This is one of several reasons for the typical warning on most equipment: "Warning – No user-serviceable parts inside".

Nettet20. mar. 2024 · The passive components (ex. capacitors, resistors, and inductors) are insensitive to voltage, within their maximum limits. The reactive components only respond to frequency changes, and resistors really don't react to much at all because they're linear components. I strongly believe in LV circuitry for non-A19 LED lighting. –

Bleed resistors are a compromise between low values (discharges quickly, but gets hots and wastes power) and high values (opposite). The voltage will reduce to safeish values within 3 or 4 time constants - especially if the amp is still drawing current for part of this time, as will usually be the case.

Nettet18. okt. 2024 · The short answer to this question is yes, generally. The higher voltage drawn by the incandescent is often sufficient current for the dimmer to work properly. But this isn't always the case, nor does Regency recommend this as a long-term solution for your dimming issues. It's more of a "Band-Aid" fix than a cure.
