Which of the following are NOT electrical components for electric circuit?
What is the power source for this circuit?
Battery
Wires
Electric socket
Magic
To have a complete electric circuit, the path must be _____
small
closed
big
open
What makes up an electric circuit?
Bulb and battery
Bulb, battery and wire
Bulb, battery and switch
Why must parts of a circuit be properly connected before the bulb can light up?
To ensure that the bulb can light up.
To ensure that the battery can produce light in a closed circuit.
To ensure that electric current can flow through the closed circuit.
This is a ________________ circuit.
closed
big
open
small
Look at the diagram. Why did the bulb not light up?
The bulb was fused.
The battery had not enough electric current to light up the bulb.
The switch was opened and prevented electric current from flowing through the circuit.
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 the light bulbs light up in this image?
Yes, both of them will
Yes, but only the one on the right
No, neither of them will
Yes, but only the one on the left
Is this a working circuit?
Yes
No
I'm not sure, I would need to test it myself.
