Understanding Series and Parallel Circuits

What happens in a series circuit if one light bulb burns out?

• The circuit becomes more efficient.

• The circuit starts to overheat.

• The other bulbs continue to work.

• All the bulbs go out.

In a parallel circuit, if one bulb fails, what is the effect on the other bulbs?

• They all go out.

• They become dimmer.

• They flicker intermittently.

• They continue to shine.

How is total resistance calculated in a series circuit?

• By dividing the resistances.

• By subtracting the resistances.

• By adding the resistances.

• By multiplying the resistances.

What happens to the total resistance in a parallel circuit as more elements are added?

• It increases.

• It remains the same.

• It decreases.

• It fluctuates.

Why is it important to understand resistance in circuits?

• To increase the voltage.

• To reduce the current.

• To make circuits more complex.

• To apply Ohm's Law effectively.
