.

Multiple Choice

What happens if one component in a series circuit breaks?

• The entire circuit stops working

• Only the broken component stops working

• The current increases

• The voltage increases

Open Ended

Explain how changing the components in a circuit can affect the electric current measured by an ammeter.

Multiple Choice

Which statement best describes a parallel circuit?

• Electricity has multiple paths to flow

• Electricity flows along a single path

• If one bulb goes out, all bulbs go out

• Each bulb gets less voltage

Multiple Choice

Which statement best describes the importance of electric current in circuits?

• It enables the transfer of energy to power devices.

• It prevents the flow of electrons in a wire.

• It increases the resistance in a circuit.

• It decreases the voltage in a circuit.

Multiple Select

Which of the following factors affect the flow of electric current in a circuit?

• Energy transferred per unit time

• Resistance in the circuit

• Type of wire used

• Shape of the circuit

in a circuit.

Multiple Choice

What is the main purpose of documenting observations during low current experiments?

• To record anomalies and expected behaviors

• To increase the voltage in the circuit

• To reduce the resistance in the circuit

• To assemble the circuit faster
