D. an insulator
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

200

The load is the part of the circuit that receives electrical energy and can be turned on.
What is the role of a load in an electric circuit?

200

The load
Which part of a circuit changes electrical energy into another form of energy?

200

They also stop working.
If one load stops working in a series circuit what happens to any other loads in the circuit?

200

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

300

Battery electric generator at a power plant photocells thermocouple
Name 3 examples of an energy source.

300

C. a fan
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

300

They are an example of a series circuit because if one of the bulbs burns out the entire strand will not light up.
Do you think Christmas Lights are an example of a series circuit or a parallel circuit? why do you think that?

300

Because the jewelry is made of something that can conduct electricity.
If you connect the wires of an electric circuit to a piece of jewelry why would the lightbulb in the circuit still turn on?

400

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.
Explain how a switch works in an electrical circuit.

400

chemical energy --> electrical energy --> sound energy
If an electrical circuit has a bell for a load and a battery for an energy source what energy conversions will occur?

400

To be determined by Ms. P
Come to the board and draw a diagram of a parallel circuit.

400

silverware metal necklaces steel wool keys aluminum foil etc.
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?

500

The load is the lightbulb, the wires are located in the electrical cord and inside the lamp, and the energy source is the electrical outlet which leads all the way to a power plant.
Where are the load, wires, and energy source located in a lamp?

500

Thermal- lightbulb, heater, etc. Sound- radio, speaker, phone, computer etc.
Name a load that can transform electric energy into thermal energy and name another load that can transform electric energy into sound energy.

500

All the loads of the robot would not work because the electricity only has one path to follow in a series circuit.
If all the loads of a robot were wired in a series circuit, what would happen if the one of the lightbulb's in the robot burned out?

500

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