I'm just starting out learning electronics and wondered if anyone could tell me whether it matters what side of an electrolytic capacitor you put a resistor to restrict the current going in and out? (The resistor and capacitor are in series.)
All the examples I've seen have put the resistor on the positive terminal of the capacitor but I'm wondering whether that's just convention. The reason I think that is because in a simple closed circuit involving a battery and LED, the resistor can go either side of the LED (in series) to restrict the current (and voltage) and protect the LED. This is because the current is the same no matter where you are in a closed circuit. With this in mind, does the same apply to a capacitor and resistor in series, i.e. does it matter what side the resistor is?
