Main Question or Discussion Point

I am confused on a question that arises in my mind:
that is "After passing the resistor the amount of current flowing through cross section of area is decrease or the energy of charges i.e Potential decreases".

I am guessing you are studying circuit theory and working you way around a circuit.

Firstly current.

What goes in at one end of a resistor comes out the other there is no change in current through the resistor.

Then the voltage, this does drop as you proceed in round the circuit. This is the potential difference across the ends of a resistor.

You can identify the current at a single point in a circuit.

You must state the voltage between two points in that circuit.
