# Interactive video lesson plan for: Series and Parallel Circuits Explained - Voltage Current Resistance Physics - AC vs DC & Ohm's Law

#### Activity overview:

This physics video tutorial explains the concept of series and parallel circuits and how to find the electrical current that flows through the circuit. It discusses Ohm's law and the relationship between voltage, current, and resistance. This tutorial review contains plenty of notes, equations / formulas, examples, and practice problems to help you on your next worksheet assignment, quiz / test or even upcoming final exam.

Here is a list of topics:
1. Ohm's Law - Voltage, Current, Resistance - V=IR Formula
2. Voltage and Current are directly proportional
3. Resistance and Current are inversely proportional
4. Definition of Voltage - Electric Potential Energy Per Unit Charge
5. Voltage Formula - Work Divided By Charge in Coulombs
6. Unit of Voltage - Volt & Unit of Current - Amps or Ampere
7. Equation of Charge = Current Multiplied By Time in Seconds
8. Definition of Current - Rate of Charge Flow Per Second
9. How To Calculate the total number of electrons flowing in a dc circuit given current in amps and time in seconds
10. Conventional Current vs Electron Flow - Flow of Positive Charge vs Negative Charge
11. Voltage - Electric Potential Difference - Electromotive Force or Electron Moving Force
12. Unit of Resistance - Ohms
13. Definition of Power - Rate of Energy Transfer
14. Unit of Power - Watts. 1 Watt = 1 Joule Per Second
15. Determining the amount of energy transferred in a circuit given time.
16. Power Delivered / Released by Battery vs Power Absorbed by Resistors - Conservation of Energy Law
17. Power Formulas / Equations - P=VI, P=I^2R, P=V^2/R
18. Charge vs Electric Current - Electricity
19. Series and Parallel Circuits Explained
20. Series Circuit - Same Current Flows Through Each Resistor - Single Pathway
21. Equivalent Resistance - Series Circuit - Req=r1+r2
22. Parallel Circuits - Multiple Paths For Electron Flow - Same Voltage Across Each Resistor
23. Equivalent Resistance of Parallel Circuit - 1/R = 1/R1 + 1/R2 + 1/R3
24. Solving Series and Parallel Circuit Problems - Finding The Current Flowing Through Each Resistor and Voltage Drop Across Each Resistor
25. Kirchoff's Voltage Law - Series Circuit - Sum of Voltages Around a Closed Loop Equals Zero
26. Kirchhoff's Current Law - Parallel Circuit - Current that enters a junction must equal the current that leaves it
27. Battery - Voltage Pump vs Resistor - Voltage Drop
28. Active vs Passive Elements
29. Internal Resistance of a Battery and EMF Calculations
30. Voltage Divider Circuit - Increasing and Decreasing Resistance
31. Voltmeter vs Ammeter Explained - High vs Low Internal Resistance
32. Voltage Drop Across Heavy Load
33. Voltage Sign Conventions and Direction of Current Flow
34. Calculating absolute and relative voltage potentials across every point in a closed circuit
35. Resistors transfer or convert electrical energy to heat energy
36. DC vs AC - Direct Current vs Alternating Current
37. Frequency of AC Voltage - Sine Wave - Number of Cycles Per Current - 60 Hz - Current reverses 60 times per second - no net flow
38. Deriving Formula Power - work over time
39. Charging and Discharging of a Battery - Direction of Polarity
40. Solving Combination Series and Parallel Circuits
41. Finding Equivalent Resistance of Series and Parallel Combined Circuits
42. Simplifying Circuits to find total resistance and current
43. Circuits With Two Batteries or Voltage Sources
