Electrical Charge


Slide 5

What is Electricity
• Form of Energy like sound or heat
• It is the movement of charged atomic particles
– Basically, electrons moving from one atom to another


Slide 6

How do you measure electricity
• Current- a flow of electricity through a
conductor (Volume)
– Amps

• Voltage – electrical force (Pressure)
– Volts


Slide 7

Electrical Sources
• Batteries
• Outlets


Slide 8

Batteries


Slide 9

Conductors & Resistors
• Conductor - object or type of material which
permits the flow of electric charges
• Resistor - anything that electricity can not
travel through easily


Slide 10

Electric Circuits
• A path for electricity to flow.
– Series – One path
– Parallel – multiple paths
