Series Circuits

Front

What is the purpose of the two metal posts on a battery?

Back

The battery needs to form a complete circuit that starts with one metal post and ends with the other metal post.

Front

How can you make a lightbulb light up in a circuit?

Back

By turning one battery so that its positive end connects to the other battery's negative end.

Front

In a series circuit, what happens to the bulbs if the wire is cut?

Back

All bulbs will go out.

Front

What happens to a circuit when the switch is opened?

Back

All the light bulbs will go out.

Front

What can be done to make a non-working circuit functional?

Back

Front

What is a series circuit?

Back

A circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What is the effect of adding more bulbs to a series circuit?

Back

Adding more bulbs increases the total resistance, which can decrease the brightness of each bulb.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity by opening or closing the circuit.

Front

What is the difference between a complete circuit and an incomplete circuit?

Back

A complete circuit allows current to flow, while an incomplete circuit does not.

Front

What happens to the current in a series circuit if one component fails?

Back

The current stops flowing, and all components in the circuit will not work.
