[Physics] Why doesn’t current decrease when it passes through a resistor

chargeelectric-circuitselectric-currentelectrical-resistance

As far as I know current is the amount of charge passing per unit time.

$$I=q/t$$

When current passes through a resistor, the resistor resists the flow of current so the amount of charge going to the resistor and leaving the resistor is the same (no charge accumulation)

but the time component increases, i.e. it takes more time for the charge to travel through the resistor.

Maybe I'm missing something here.

My question is related to If the current is increased, is there more charge flowing or is it moving quicker?

If the current is larger more charge flows through the resistor per second.

What you are missing is the fact that the current through your resistor is controlled not only by the resistance of your resistor but the circuit elements of a complete electrical circuit of which your resistor is one part.

Your resistor not only has an effect on the current passing through it but also the currents passing through other circuit elements to which it is connected.
In the end as there is no source or sink of charge within your resistor, the current entering your resistor coming from the circuit to which it is connected to is equal to the current leaving the resistor and that current is going into the circuit to which your resistor is connected to.
