What is a series circuit?

Back

A series circuit is a type of electrical circuit where the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, allowing multiple pathways for the current to flow.

What happens to the current in a series circuit when more components are added?

Back

In a series circuit, adding more components increases the total resistance, which decreases the overall current.

Front

What happens to the current in a parallel circuit when more components are added?

Back

In a parallel circuit, adding more components decreases the total resistance, which increases the overall current.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push electrons through the circuit.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the path for current to flow.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow uninterrupted.

Front

What is the direction of electron flow in a circuit?

Back

Electrons flow from the negative pole to the positive pole.

What happens if one light bulb is removed from a series circuit?

Back

If one light bulb is removed from a series circuit, the entire circuit is broken and all bulbs go out.

Front

What happens if one light bulb is removed from a parallel circuit?

Back

If one light bulb is removed from a parallel circuit, the other bulbs remain lit.
