Does a resistor affect the flow of current?
Does a resistor affect the flow of current? A circuit always has a bit of resistance, no matter if it has resistors or not in it. So yes, the resistor does reduce the current. (But the current flowing into the resistor is still the same as the current flowing out.) This is one of the mindset shift a beginner has to go through when learning electronics. Does resistor affect voltage or current? Resistors affect both current and voltage. They do it in a linear fashion. The voltage across each resistance will vary directly in proportion to the current that is...
