In a simple series circuit.what happens to the brightness of the lightbulbs as we add more of them? the do not change They become less bright they become brighter

Answer 1

They become less bright

Answer 2

## Step 1: In a simple series circuit, the components (in this case, lightbulbs) are arranged in a single, continuous path. The same current flows through all the components in the circuit. ## Step 2: When we add more lightbulbs to the series circuit, the total resistance of the circuit increases. This is because in a series circuit, the total resistance is the sum of the individual resistances. ## Step 3: According to Ohm's law, which states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance, an increase in resistance results in a decrease in current. ### Ohm's Law: \(I = \frac{V}{R}\) ## Step 4: The brightness of a lightbulb in a circuit is determined by the power dissipated in the bulb. Power is given by the product of the current and the voltage across the bulb. Therefore, a decrease in current results in a decrease in power, which in turn results in a decrease in brightness. ### Power Dissipation: \(P = IV\)
