Electricity and Circuits

Front

What is required for electrical energy to flow?

Back

A closed circuit is required for electrical energy to flow.

Front

What is the measure of potential energy stored in a battery called?

Back

Voltage is the measure of potential energy stored in a battery.

Front

Which of the following is NOT a conductor: Water, Aluminum, Wood, Penny?

Back

Wood is NOT a conductor.

Front

What have electrical engineers developed to make computers smaller?

Back

Electrical engineers developed miniature circuit boards to make computers smaller.

Front

In which type of circuit does each component have its own path for the current to flow?

Back

In a parallel circuit, each component has its own path for the current to flow.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily.

Front

What is the function of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is a series circuit?

Back

A series circuit is 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 resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current.
