Electricity and Circuits

Front

What is static electricity?

Back

A buildup of electric charge on an object that remains stationary.

Front

Why can pennies be used to make a battery?

Back

Because they are conductors.

Front

In a series circuit, what happens to the brightness of lightbulbs when more are added?

Back

The brightness decreases; they do not get brighter.

Front

Which bulb will be brighter in a circuit with different voltages?

Back

The bulb with more voltage will be brighter.

Front

What is the electrical charge of an object with equal positive and negative charges?

Back

Neutral or no charge.

Front

What is an electric circuit?

Back

A closed loop that allows electric current to flow.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric current to flow easily, while insulators do not.

Front

What is voltage?

Back

The measure of electric potential energy per unit charge.

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so the same current flows through all of them.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, allowing multiple paths for current.
