What is the main difference between a series and a parallel circuit in terms of the pathways for electricity to flow?

In a series circuit, there is only one pathway for electricity to flow, while in a parallel circuit, there are multiple pathways.

In a series circuit, if one component fails (e.g., a light bulb burns out), what happens to the rest of the circuit and why?

The entire circuit will stop working because the circuit is broken, and there is no longer a complete path for the current to flow.

The rest of the circuit continues to function because the other components still have a complete path for the current to flow.

Adding more resistors in series decreases the total current in the circuit.

Adding more resistors in parallel increases the total current in the circuit.

Series and Parallel Circuits

3 key concepts

1
In a series circuit, the current is the same through every component, and all components must be working for current to flow.
2
In a parallel circuit, the total current is the sum of the currents in each parallel pathway, and the voltage drop is the same along each pathway.
3
Adding more resistance in a series circuit will decrease the amount of current, resulting in dimmer light bulbs.
