Parts of a Circuit
A student is constructing an electrical circuit. Which of the following can provide energy for the circuit? A.battery B. Wire C. light bulb D.buzzer
Answer: A. a battery
The type of energy a circuit always starts off with is ________________ energy.
Electrical
In a parallel circuit electricity has ______ path(s) to follow.
more than one
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
What is the role of a wire in an electric circuit?
The wire allows the energy to flow through.
Which part of a circuit changes electrical energy into another form of energy?
The load
If one load stops working in a series circuit what happens to any other loads in the circuit?
They also stop working.
Which material will best conduct electricity? A. plastic B. rubber C. wood D. silver
D. silver
What type of circuit has more than one path for energy to flow?
Parallel circuit
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
Do you think Christmas Lights are an example of a series circuit or a parallel circuit? why do you think that?
They are an example of a series circuit because if one of the bulbs burns out the entire strand will not light up.
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.
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 electricity cannot flow.
If an electrical circuit has a bell for a load and a battery for an energy source what energy transformations will occur?
electrical energy --> sound energy
On a piece of paper or on Classkick, draw a diagram of a parallel circuit.
To be determined by group
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 necklace, steel wool, keys, aluminum foil etc.
What type of circuit only has one path for energy to flow through?
Series circuit
Name an example of an object that can transform electric energy into thermal energy and name another example that can transform electric energy into sound energy.
Thermal- lightbulb, heater, etc. Sound- radio, speaker, phone, computer etc.
If all the loads of a robot were wired in a series circuit, what would happen if the one of the lightbulbs in the robot burned out?
All the loads of the robot would not work because the electricity only has one path to follow in a series circuit.
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!
