Question

Is it true or wrong to say that Current decreases when passing through a resistor and then increases again upon exiting? Provide a good argument for your answer, whether it is yes or no.

Answer 1

Technically, yes, but I would reword it differently.

Step-by-step explanation:

You are right- a current essentially 'decreases' when it passes through a resistor. The only issue with your answer is the wording.

--->Instead of saying the current 'decreases,' it's more so of losing its electric potential energy or voltage.

----->Additionally, when a current of any sort enters and exits the presence of a resistor, its electric charge of voltage remains the same.

--------->The only change that occurs is the change in the electrons losing their electric potential energy (namely, voltage- because that energy is converted into heat energy).

So, one way to reword what you've said is:

When a current flows through a resistor, its electrons lose their electric potential energy (voltage) as it is converted to heat energy. Upon exiting the resistor, the electrons offset themselves (convert the heat energy back to their original voltage or electric potential energy) accumulated before contact with the resistor (back to normal).

Hope this helps <3.
