I'm new to this topic... what's the benefit of the last configuration using a transistor? I mean, why not use a current limiting resistor on the component to drive instead, and avoid the other components? Thank you!

[@ovalwingnut]

You are gifted at explaining these circuits my friend :)

[@hadibq]

so true!

[@mparwezk]

Your videos are very educative and also well explained. Very good keep it up

Ludic can I use 6kv 0.001uf capacitor for high voltage

[@Theo0x89]

Let's say I want to minimize energy loss. How low can I go with R, adjusting the voltage divider accordingly? How high can the resistor values of the divider go?

Hello this is off topic but I'm struggling with making a driver circuit with a PNP transistor. Do you have any videos on that or can point me in the right direction

[@NemencioRas]

Can a similar settings work with a 4volt lithium-ion battery?

[@TerminalJack505]

In your schematic you say I = V / (2R) but it should be I = V / R. 6 / 330 = 0.0182.

[@lutfijd]

In the schematic the only source of voltage is 12V, and voltage on non inverting is 6v. thus the division.

[@TerminalJack505]

@@lutfijd I stand corrected. I was calculating the current based on the voltage at the non-inverting input.

[@badraa7838]

why does an led need a constant current?

[@Basement-Science]

Because the current through an LED increases _exponentially_ with more voltage, making it impossible to control.

Maybe to have a steady glow?
