Question

connecting multiple electrochemical cells (lemons) together one after another results in ______ current flowing through the circuit if you change nothing else.
more
less
the same

Explanation:

When electrochemical cells (like lemons) are connected in series (one after another), the total voltage of the circuit increases (since each cell's voltage adds up, \( V_{total}=V_1 + V_2+\dots+V_n \) for \( n \) cells). According to Ohm's Law (\( I = \frac{V}{R} \)), if the resistance \( R \) of the circuit remains constant (as "nothing else" is changed) and the voltage \( V \) increases, the current \( I \) flowing through the circuit will also increase. So connecting multiple lemon cells in series results in more current.
