What is an electrical circuit?
a whole bunch of wires
a broken path that electric charges can flow
a circuit board
a complete, unbroken path through which electric charges flow
When a switch is open...
the circuit is working and gives energy
the circuit is broken and charges cannot flow
the circuit is turning lights on
I don't know...ask Ms. Cednick
Will this circuit light the bulbs?
Yes, both will light up
Yes, but only the one on the right
Yes, but only one on the left
No, neither of the bulbs will light up
Is this a working circuit?
Yes
No
I'm not sure, I would need to test it myself.
This is an example of a _______ circuit
open
series
parallel
square
This is an example of a ______ circuit
Series
Parallel
Open
Dihexihedral
What is not needed in order to create a working circuit?
battery (power source)
lightbulb
current
closed circuit
This circuit does not work. Which of these would allow the bulbs to light?
Open the switch and then connect the two wires that are attached to the wood block
Switch the positions of the two wires that are connected to the battery and then open the switch
Move the switch closer in the circuit to the battery
Connect the two wires that are attached to the wood block
Why is electrical wiring usually made from copper?
Because copper is shiny
Because copper conducts electricity
Because copper is not magnetic
Because copper insulates electricity
What is a current?
A steady flow of electricity.
A short burst of electricity.
A wire along which electricity flows.
A power source that supplies electricity.
What is the function of a power source in a circuit?
It provides a steady source of static electricity.
It provides a way for the circuit to be broken.
It provides a path along which the electricity can flow.
It provides a steady flow of electrons.
Which of the following is an example of a load?
What happens if you disconnect a circuit from its positive terminal?
The electrons shoot out from the negative terminal.
The electrons stop flowing, and the current stops.
The current reverses direction.
Nothing happens.
1. Which of the following statements best compares the functions of parts A & C?
Part A generates the energy needed for electricity, while part C conducts the flow of electricity.
Part A absorbs the flow of electricity, while part C generates the energy needed for electricity.
Part A opens and closes the flow of electricity, while part C transfers the flows of electricity.
Part A is the device activated by the electricity, while part C controls where the electricity goes.
2. Which of the following statements best describes parts B & D?
Part B is the conductor, or wire, and Part D is the battery, or load
Part B is the circuit or conductor, and Part D is the load, or switch
Part B is the battery, or power source, and Part D is the bulb, or load
Part B is the battery, or load, and Part D is the bulb, or power source
When you have a circuit that has the different parts of the circuit on separate paths or branches, it is called a ____
series
open
parallel
closed
17. What type of circuit is shown?
series
parallel
What will you do if you are told by your teacher to close the circuit?
turn the switch off
turn the switch on
disconnect the circuit
add more bulb in the circuit
In a series circuit, current flows in only one path while in parallel circuit, there are multiple paths. This description is
True
False
At home, you noticed that a portion of an electrical wire is worn out, exposing its metallic part. What do you think might happen if you will just ignore this problem?
short circuit may happen
circuit is of better condition
overloading may not happen
nothing happens when someone touches the wire
What is a circuit breaker?
A type of light switch.
A switch used in an electrical appliance that uses large current.
Used to turn on or off the electrical supply to the whole house.
Used to switch off the electrical supply to one part of the circuit when current in that part of the circuit is too large.
Which is a result of overloading of electrical appliances?
high performance of equipment
inadequate current supply
overheating of wires and fire may occur
none of the above
What kind of circuit is in the picture?
open circuit
closed circuit
short circuit
A path for electric current to flow with very low resistance. As a result, a very high amount of current flows causing wires to get very hot. This can cause a fire.
electric circuit
short circuit
long circuit
series circuit
