Electricity & Circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

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

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

Back

If one light bulb goes out in a series circuit, the entire circuit is broken and all lights go out.

Front

What happens if one light bulb goes out in a parallel circuit?

Back

If one light bulb goes out in a parallel circuit, the other light bulbs remain lit because they have separate pathways for current.

Front

How many pathways are there for electrons to flow in a series circuit?

Back

There is only one pathway for electrons to flow in a series circuit.

Front

How many pathways are there for electrons to flow in a parallel circuit?

Back

There are multiple pathways for electrons to flow in a parallel circuit.

Front

What is the role of a battery in a circuit?

Back

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

Front

What is a load in an electrical circuit?

Back

A load is any component in a circuit that consumes electrical energy, such as a light bulb or resistor.

Front

What is the difference between an open circuit and a closed circuit?

Back

An open circuit has a break in the path, preventing current from flowing, while a closed circuit has a complete path allowing current to flow.
