If you add a fourth resistor in the series circuit, how will it affect the current through each resistor and potential difference across each resistor?

Question

snitchseeker1496 · Answer

Your current won't be affected right? since they are equal all throughout the resistor?

huclogin · Answer

I think the current in the four resistors  is lower than the current in the three resistors since the problem doesn't mention the change of the total electric potential,thus the potential on each resistor is 1/4 lower.

Since we add a resistor to the circuit, that implies that we are trying to decrease the current keeping the cell/battery voltage same. So that means current through each of them decreases and potential diff across each of them also varies accordingly.

Thank you :)

How about if it is in parallel circuit?

radar · Answer

If you had three resistors in parallel, and then added a fourth resistor in parallel with the original three, then you have added an additional path for current, increasing the total current and decreasing the total resistance.

Thank you guys for helping me :)

radar · Answer

That is of course assuming your source voltage remained the same.
