What is Electricity?
Electircal energy
Is the movement of electrons from one
atom to another!
–
So..what’s an electron?
– And where do all these extra electrons
come from?
The Atom
Neutrons
Protons
Electrons
When can Electrons Flow?
Can all atoms give up their electrons?
–
Some atoms electrons are loosely held
others hold on to their electrons well
Atoms that give up electrons are called
conductors
Atoms that do not give up electrons are
called insulators
Electron Flow
Current: is the flow of electrons
The measure for the flow of current is
amperes or amps.
The electrical symbol is “A”

What makes electrons flow?
Voltage is the measurement of electron
pressure
Voltage is measured in…VOLTS!
The electrical symbol is “V”
Think back to the Solar Car
Voltage has what effect on an electric
motor?
Voltage effects motor
speed
Current/Amperage has what effect on
an electric motor?
Amperage effects motor
torque
Resistance
Resistance is a force that opposes the flow of
electrons. Measured in Ohms()
