So I've read that using one resistor to limit current to two or more LED's in parallel is bad practice, so I wondered what about this kind of circuit:
Is this also bad practice?
Each LED has it's own current limiting resistor, but the current is being limited further by a resistor in series. Are there any differences compared to just having each LED connected in parallel directly to the voltage source with a 355Ω Resistor?
Also (just to double check I am doing my calculations right as I am still a student learning this stuff), assuming each LED has a forward voltage of 2V, is each LED drawing about 20mA here (7V across resistors, Rtotal = 355Ω so 7V / 355Ω = 0.0197 Amps)?
