1. CHARACTERISTICS OF ELECTRICITY

2. LEARNING GOAL 1 Describe the sources and transformation of electrical energy

3. Words to Know Hydro Solar Wind Geothermal Wave/tidal Biomass Nuclear
Fossil Fuels
*Describe process of transformation

4. LEARNING GOAL 2 Explain how electric charges flow from an energy source to a device that uses energy

5. Words to know Electric potential energy Electrochemical cells Current
Electrodes
Electrolyte
Energy
Volt
Voltage
Current
Amperes
Circuit
Load

6. Identify the components of a circuit
Relate the charge on electrons to electron flow in a circuit (ie from negative to positve)
Define current in terms of the amount of electric charge that passes a point in a given time interval
Define voltage as the electric potential difference

7. LEARNING GOAL 3 Utilize ohm’s law to relate resistance, voltage and current in a circuit

8. Words to know
Resistance
Resistor
Ohm
Ohm’s Law

9. - A resistor resists the flow of electric current
Ohms Law states that the resitance of a material is equal to the ratio of voltage divided by current
R=V I

10. LEARNING GOAL 4 Differentiate between circuits in series and parallel in terms of current, voltage and total resistance

11. Words to know
Junction point
Parallel circuit
Series circuit

12. In Series:
Current remains the same, but voltage changes
Increasing the number of resistors in series increases the total resistance
In Parallel:
Current changes, but the voltage stays the same
Increasing the number of resistors in parallel decreases the total resistance
