current and voltage

sneha_28

I have a basic doubt regarding concepts of current. we know that a resistor is a current limiting device. But when it is connected in series with a voltage source,current remains the same.
Why doesn't the current change even after passing through a series of current limiting resistors? what am i missing out here?

What makes you think that the current doesn't change when the resistance changes? What's your understanding of Ohm's law?

The way the question was worded implies adding resistance, but I think the question was why isn't the current different in different parts of the circuit.

Water analogy: why isn't flow rate lower after an obstruction in a pipe?
