Electricity and Circuits

Front

What are conductors?

Back

Materials that allow electric current to flow through them easily, such as metals like copper and aluminum.

Front

What are insulators?

Back

Materials that do not allow electric current to flow through them easily, such as rubber, glass, and plastic.

Front

What is a series circuit?

Back

A circuit where components are connected in a single path, so the current flows through one component to get to the next.

Front

What is a parallel circuit?

Back

A circuit where components are connected in multiple paths, allowing current to flow through more than one path.

Front

What happens to the brightness of bulbs in a series circuit when more bulbs are added?

Back

The brightness decreases because the total resistance increases, reducing the current.

Front

What happens to the brightness of bulbs in a parallel circuit when more bulbs are added?

Back

The brightness remains the same because each bulb has its own path for current.

Front

What is voltage?

Back

The measure of electric potential difference between two points in a circuit, which drives the current.

Front

What is a battery?

Back

A device that converts chemical energy into electrical energy, providing a source of voltage in a circuit.

Front

What is current?

Back

The flow of electric charge in a circuit, measured in amperes (A).

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in ohms (Ω).
