Question

what happens when you add more batteries to circuits?

• series -
• parallel -

Explanation:

Analyze series battery connection

$$ V_{\text{total}} = V_1 + V_2 + \dots + V_n $$

Adding more batteries in series increases the total voltage of the circuit.

Analyze parallel battery connection

$$ V_{\text{total}} = V_1 = V_2 = \dots = V_n $$

Adding more batteries in parallel keeps the total voltage the same but increases the overall capacity (lifespan) of the circuit.

Answer:

What happens when you add more batteries to circuits?

• Series - The total voltage increases.
• Parallel - The total voltage remains the same, but the battery capacity (lifespan) increases.
