Measuring Voltage and Current in a Circuit

If the goal is to increase voltage, how should multiple batteries be connected?

• In parallel

• In series

• Randomly

• In a triangle

What is the role of the switch in the circuit?

• To measure voltage

• To stop or allow the flow of current

• To connect the batteries

• To change the circuit board

What happens to the flow of electrons if a more conductive material is used?

• The flow of electrons decreases

• The flow of electrons remains the same

• The flow of electrons increases

• The flow of electrons stops

What is the formula the conductivity unit rate?

• Voltage / Current

• Voltage • Current

• Voltage + Current

• Current / Voltage

What is the formula for power?

• P = Voltage • Current

• P = Voltage / Current

• P = Current / Voltage

• P = Voltage + Current
