Circuit Design

Which of the following is true about electrical circuits?

• They have to involve a wire made of insulating material.

• Every circuit needs to have a switch that can stop and start the flow of electricity.

• An open circuit works as long as the wire connects a bulb to the positive end of a battery.

• Electricity can only flow if the circuit is a closed loop.

What is wrong with this circuit so that it does not work?

• It is missing a switch.

• The light bulb needs to be on the other side of the circuit.

• The path needs to be connected to the battery.

• The light bulb needs to be touching the battery.

A student builds a circuit with a fan, a battery, and some wire. The battery is being drained too quickly. Which of these should the student add to the circuit so the battery drains more slowly?

• a switch, so the fan can be turned on and off

• a lightbulb, to show when the battery is getting low

• a different battery that provides less energy

• a different fan that requires more power

A student makes two circuits, P and Q, using batteries, bulbs, switches, and connecting wires. Which circuit will NOT produce light?
