# How can current remain same when potential difference decreases?

According to Ohm's law, $$\text{potential difference} = \text{resistance}\times\text{current}$$ Also, current remains the same everywhere.

Now when current passes through a bulb, the electric potential decreases because $$\text{electric potential} = \frac{\text{joules}}{\text{coloumb}}$$ and some of the electric energy is converted into light energy by the bulb. So after passing through a bulb, the number of joules of electric energy a single charge carries will get lower, i.e electric potential decreases which means the potential difference decreases. So by Ohm's law, the current should decrease too. This contradicts the fact that current remains same everywhere.

So how can current remain same when potential difference decreases?
