5.  What must we do to create the energy (static)?  What happens to the electrons once they are charged?  What do we make when we use the three processes that charge an object? How does the transfer of energy create electricity?

6. 1.Series circuit- there is only one path for the electrons to take. 2.Parallel circuit- the different parts of the electric current are on separate branches. Which on is Which?

8.  Electric Current – net movement of electric charges in a single direction through a wire or conductor.  Voltage Difference (Electric potential difference) – force that causes electric charges to flow; charges flow from high voltage to low voltage.

9. 1. Making electric charges move → Voltage- the work done per unit charge as a charge is move between two points in an electric field. → Unit- Volt (V) → Symbol- V (the unit and symbol should not be confused) → Equation: V = current x resistance

10. 2. Electric Current → Current- the amount of a charge that passes a given point per unit of time → Unit- Ampere (A) → Symbol- I → Currents move by means of direct or alternating currents.

11. → Direct current- (DC) occurs when the electrons always flow in one direction → Alternating current- (AC) occurs when electrons move back and forth reversing the direction regularly.

12. 3. Resistance → Resistance- the opposition to the flow of electric charge. → Symbol- R → Unit- Ohms ( Ω ) → nonconductors cause the most resistance. (ex: rubber, wood, etc.) → Superconductors- has a resistance of zero. (ex: metals like copper)

13. → Ohm’s Law states that the current in a wire (I) is equal to the voltage (V) divided by the resistance (R) Recap of potential difference formula: Electric potential difference aka voltage = current x Resistance V=IR Units: V=A Ω

14. 1. What is the unit for electric potential difference? Another words voltage. 2. What are the units for voltage, current & resistance? 3. Name two nonconductors and one superconductor. 4. Describe the difference between DC circuits and AC circuits. 5. What is the oxidation number for Br?
