Hello guys I just have a curious question.
say I have 2 LEDs,
:each running with a 330 ohm resitor in series
:each running off the same voltage (5volts in this case)
:both running under a PWM signal (25% in this case)
The only differrence is that the operating frequency for one LED is that it is running at 10,000 hertz and the other is running at 500 hertz.
now for the question: Which one will appear brighter and why???
p.s. I'll try and post the circuit asap, but this is the question simplified in itself.sorry guys
