Electricity

What is a circuit?

• A circuit is a type of dessert

• A circuit is a closed loop through which an electric current can flow.

• A circuit is a type of clothing

• A circuit is a type of animal

Name three examples of conductors.

• silver

• iron

• plastic

• copper, aluminum, gold

Give two examples of insulators.

• plastic

• metal

• rubber and glass

What does the symbol for a battery look like?

• A circle with a dot in the center

• A triangle with a zigzag line

• A rectangle with a long line on the top and a shorter line on the bottom

• A square with a wavy line

Draw the symbol for a light bulb.

• The symbol for a light bulb is a circle with a straight line coming out from the top, a wavy line inside the circle, and short lines around the circle to represent light rays.

• A square with a zigzag line inside

• A triangle with a circle inside

• A star with a spiral shape

Explain the difference between an open circuit and a closed circuit.

• An open circuit is used for high-power applications, whereas a closed circuit is used for low-power applications.

• An open circuit has a gap that prevents the flow of electricity, whereas a closed circuit has a complete path for electricity to flow.

• An open circuit is always safe to touch, but a closed circuit can be dangerous.

• An open circuit allows electricity to flow freely, while a closed circuit restricts the flow of electricity.

Why is it important to use insulators in electrical wiring?

• Insulators are important to prevent the flow of electricity to unwanted paths, reduce the risk of electric shock, and maintain the integrity of the electrical system.

• Insulators have no impact on the safety of electrical wiring

• Insulators are only used for decoration in electrical systems

• Insulators increase the flow of electricity in wiring

What is the purpose of a switch in a circuit?

• To make the circuit more colorful

• To control the flow of electricity in a circuit.

• To keep the circuit warm

• To play music in the circuit

Describe how electricity flows in a circuit.

• Electricity flows from the power source to the load and then to the ground.

• Electricity flows from the power source through a conductor to the load and back to the power source.

• Electricity flows from the power source to the load and then dissipates into the air.

• Electricity flows from the load to the power source and back to the load.

What is electricity?

• A zap from friction
• A thunderbolt thrown by Zeus
• Moving electrons
• Energy from the air
