Energy Transformations in a Circuit Part 1

100

A student is constructing an electrical circuit. Which of the following can provide energy for the circuit? A.electric generator B. Wire C. light bulb D.buzzer

Answer: A. an electric generator

200

Name something that can transform electric energy into sound energy.

Fan, tv, phone, etc..

300

Name 3 examples of an energy source.

Battery electric generator at a power plant photocells thermocouple

400

Explain how a switch works in an electrical circuit.

When the switch is on the circuit is closed so electricity can flow. When the switch is off the circuit is open so electricty cannot flow.

500

A circuit is open. There is a missing space. What item can you choose to complete the circuit and turn on the light?

anything that allows electricity to flow through (magnetic)

Energy Transformation in a Circuit

100

The type of energy a circuit always starts off with is ________________ energy.

Electrical

200

What is needed to create an electrical circuit?

Wires, energy source, switch, light (optional)

300

Which device can be added to an electrical circuit to convert electrical energy into mechanical energy? A. a switch B. a lightbulb C. a fan D. a speaker

C. a fan

400

If an electrical circuit has a bell and a battery for an energy source what energy conversions will occur?

chemical energy --> electrical energy --> sound energy

500

Name something that can transform electric energy into thermal energy. 

Thermal- lightbulb, heater, etc. 

Series Circuits

100

In a closed circuit electricity _______  (will/will not) flow through a form a complete path. 

will

200

If one energy source stops working in a series circuit what happens to any other energy sources in the circuit?

They also stop working.

300

What happens in an electrical circuit if the switch is open?

The electricity is not able to completely flow through the circuit. The light will not light.

400

Draw an example of a closed electrical circuit.

To be determined by the teacher. 

500

In a circuit, there is an energy source, wires and a light. The circuit is closed, but the light will not light. What may be a possible reason for it not lighting up?

The light bulb has burned out, or the energy source (battery) has lost it's power. 

Conductors and insulators in a circuit

100

Some students test a plastic spoon as a connector in an electrical circuit. Electricity does not flow in the circuit. Plastic is most likely... A. a load. B. an energy source C. a conductor D. an insulator

D. an insulator

200

Which material will best conduct electricity? A. plastic B. rubber C. wood D. silver

D. silver

300

If you connect the wires of an electric circuit to a piece of jewelry why would the lightbulb in the circuit still turn on?

Because the jewelry is made of something that can conduct electricity.

400

Ms. P wants to make an electric circuit but she is fresh out of copper wire. What are 3 other household items that she could use in place of wire to carry the electricity to the load?

silverware metal necklaces steel wool keys aluminum foil etc.

500

Why do electricians use wire that is coated in plastic when they are making new circuits?

This is because the wire can be dangerous to handle and can shock humans if they handle it when the circuit is on. The plastic coating helps to protect the electricians and us!
