Why does the current remain the same in a series combination of resistors while the potential difference (p.d.) remains different across each resistor?
Answer (2)
Current at all points of a series circuit must be the same, because there's no place in the circuit where electrons are being manufactured, and no place where they're leaking out and falling on the floor. The nimber of electrons that leaves the loop is the same number that entered it.
I'm not sure what is nmeant by "p.d. remains different" .
In a series circuit, the current remains the same across all resistors because there's only one path for the current to flow. However, the potential difference varies due to the different resistances of each resistor, which dissipate energy and create voltage drops. The total voltage from the power source is equal to the sum of these individual voltage drops.
