Charge Vocab
Electricity is the flow of these
Electrons
This will flow through a circuit as long as none of the wires are broken
Current
In Ohm's Law "V" stands for this
voltage
Circuit
Magnetite will point this direction when allowed to turn.
North
This is a material that does not allow electricity to flow easily
This supplies energy to an electric circuit.
A Battery.
In Ohm's Law "R" stands for this
Resistance
As resistance in electric current increase current in the circuit _________.
Decreases
These are the two poles on magnets.
North and South
A material that allows electricity to flow easily
Conductor
This is the measure of how difficult it is for electrons to flow through a material.
Resistance
In Ohm's Law the unit we use for current is this
Amps
kilowatts
The area around a magnet through which the magnetic force is exerted.
Magnetic field
Static electricity
This is the measure of electrical potential
Voltage
The unit we use for resistance is this.
Ohms
Circuits in homes and buildings have ________ that limit the amount of current in the wiring.
Fuses or circuit breakers
This is used to detect Earth's Magnetic Field
These form when an atom gains or loses electrons
Ions
Electrons move in a circuit and have millions and millions of___________.
Collisions
This is the formula for Ohm's Law.
V=IR
I= V/R
R= V/I
These are the 2 kinds of circuits
Series and Parallel
The Earth's magnetic field is called this.
Magnetosphere
