Static & Current Electricity
This type of electricity occurs when there is an imbalance of charges on an object.
What is static electricity
Materials like copper and aluminum are classified as these because current flows easily through them.
What are conductors
These are the two magnetic poles found on every magnet.
What are the north and south poles
A wire wrapped around a nail and connected to a battery creates this temporary magnet.
What is an electromagnet
A circuit in which electricity can flow freely is called this.
What is a closed circuit
This is the flow of electric charge.
What is electric current
Materials like rubber and plastic have high resistance and are called these.
What are insulators
A material that stays magnetic even when not near other magnets is called this.
What is a permanent magnet
A magnet made with electric current and wires is called this.
What is an electromagnet
Electric current always flows from this level of voltage to the opposite level.
What is higher to lower voltage
Electric current is measured in these units.
What are amperes (amps)?
A complete path through which electric current can travel is called this.
What is an electric circuit
When distance between magnets increases, magnetic force does this.
What is weaken
As more coils of wire are added to an electromagnet, this increases.
What is magnetic strength
If a circuit does not allow energy to flow because the path is incomplete, this type of circuit is present.
What is an open circuit
Stacking batteries causes this electrical quantity to increase.
What is voltage
When this type of circuit occurs, the current stops because the path is broken.
What is an open circuit
If you cut a magnet in half, each piece still contains these.
What are two poles
When two south poles face each other, they do this.
What is repel
These particles move through wires to create electric current.
What are electrons
Energy will not flow when this does NOT exist between two points in a circuit.
What is a voltage difference
This determines how much current flows through a circuit at a given voltage.
What is resistance
A magnet attracts objects made of this metal.
What is iron
A compass needle points north because Earth’s geographic north is actually this magnetic pole.
What is the south magnetic pole
This happens to the current when resistance becomes high in a circuit.
What is the current decreases
