Excellent explanation and pace, without "hmms" or false starts. I have looked a dozens YT vids on topic of LEDs and resistance. This is by far the best in manner and content.

I am trying to determine this little scenario. A 30V/5A adjustable PSU sends 15V to an OFF-ON toggle. The toggle is flipped to ON. I want a green 3V/.02aM indicator LED to light up while also sending 15V onward to a potentiometer. Is this possible, or will the voltage entering the "Pot" be less than 15V? Many Thanks!

Correct me if i am wrong , in your circuit, isn't the led should be drawn the other way round, the longer line of the battery should be +, the shorter should be -, ( on the paper)

What if the power supply is at the same voltage rating as the led.. lets say i have a 3V led with a 3V power source, should i need a resistor, because lets say given that the led's current rating is 30mA .. i still need a resistor don't I?

I have noticed that the resistor used in LED indicators for 220V AC appliances like mosquito repellents uses 100k resistor but according to the formula [Resistance = (Supply Voltage - LED Voltage)/LED Amps] the resistor should be 12k (approx) but why 100k is used?

The lighting detracts because there is not enough contrast between the whiteboard and the markers.The cameraman is not close enough and is shooting down on her. She can slow down. Also, it helps to have the "slides" prepared. I will call this a Good Try.

Romans 10:8-10 [8]But what does it say? The Word (God's message in Christ) is near you, on your lips and in your heart; that is, the Word (the message, the basis and object) of faith which we preach, [Deut. 30:14.] [9]Because if you acknowledge and confess with your lips that Jesus is Lord and in your heart believe (adhere to, trust in, and rely on the truth) that God raised Him from the dead, you will be saved. [10]For with the heart a person believes (adheres to, trusts in, and relies on Christ) and so is justified (declared righteous, acceptable to God), and with the mouth he confesses (declares openly and speaks out freely his faith) and confirms [his] salvation.

you can also do 2. even white LEDs can light up already at a voltage of 2.6 volts. and red, yellow with even less.
