Circuits containing identical lightbulbs in series and parallel configurations.
Two identical lightbulbs, each modeled as a resistor of resistance \(R\), are connected to an ideal battery of potential difference \(V_0\). In Configuration 1, the two bulbs are connected in series. In Configuration 2, the same two bulbs are reconnected in parallel across the battery. Which of the following correctly compares the total current drawn from the battery in Configuration 2 to Configuration 1 and explains why individual bulbs burn brighter in Configuration 2?
