Why is the current constant in a series circuit?

Click For Summary
SUMMARY

In a series circuit, the current remains constant throughout due to the principle of charge conservation. Each resistor in the circuit introduces resistance, but the total current flowing through the circuit is determined by the total resistance and the applied voltage, as described by Ohm's Law (V = IR). The voltage drop across each resistor varies depending on its resistance, but the current remains unchanged. This fundamental behavior is essential for understanding electrical circuits.

I know that in a series circuit the current is the same amperage though out the circuit. What does not make sense to me though, is why it should be that way. For example, if one had a series circuit with just resistors in it, it seems that the resistors would each change the flow of the current by way of providing resistance. I hope that that made sense.

Think of the series resistors as one resistor. So whatever current will flow in, it must flow out. But what will be different is the voltage across every resistor.
 
Thanks waht.
