What provides the energy to an electromagnet?
switch
wires
battery
the bulb
When all parts of the circuit are connected it is a ______ circuit.
open
closed
parallel
series
The flow of charged particles through a circuit is:
Protons
Resistance
Electric Current
Magnetic
Voltage is:
The amount of potential energy between two points on a circult.
It is the rate at which charge is flowing.
It is a material’s tendency to resist the flow of charge.
Resistance is:
The amount of potential energy between two points on a circuit.
It is a material’s tendency to resist the flow of charge.
It is the rate at which charge is flowing.
A circuit is:
A bulb linked to a wire.
A closed loop that allows a resistor to stop the energy.
A closed loop that allows charge to move from one place to another.
A copper wire with a switch.
What does simple circuit is made up of?
A wire, a switch and a battery
A wire, a bulb and a fuse
A battery, a wire and a bulb
A wire, a switch and a battery
Why can fuses be important in circuits?
Because they measure the current flowing through a part of the circuit.
Because they break the circuit if too much current flows through it.
Because they reduce the strength of the current in one part of the circuit.
A parallel circuit:
Uses a single path to connect the electric source to the output device.
Uses more than one path to connect the electric source to the output device.
Provide more voltage then one source alone can’t produce.
The pressure of the water in a tank can be compared to:
The resistance
The current
The electromotive force from the battery
Electromagnetism:
is vital to prevent the universe from falling apart.
makes things feel solid if even though in reality they consist mostly of empty space.
holds atom together so that they can form molecules.
All of other the options are correct.
Electromagnetism is based on:
The fact that the motion of electric charge can produce magnetic fields and changing magnetic field can produce electric currents.
The fact that the motion of a magnet can produce magnetic fields and changing magnetic field can produce electric currents.
The fact that electricity can produce a magnet.

A device for opening or closing the flow in a circuit is _______.
an insulator
a battery charger
a switch
a resistor
Will the light bulb in this circuit light? Why or why not?
yes, because it has two batteries
no, because the switch is open
yes, because it is in a circuit
no, because the bulb is burned out
