Understanding Electrical Circuits: Series and Parallel Relationships

This guide explores the concepts of electrical barriers in series and parallel circuits, detailing how voltage and resistance relate to current flow. It covers essential rules like the Wheatstone Bridge for determining resistance substitutions, and provides practical examples for calculating voltage drops and currents in various circuit configurations. Key concepts like Kirchhoff's laws and the relationship between energy and power in electrical systems are also highlighted, enabling a better grasp of closed versus open circuit functionalities.

  1. Direct Current Series

  2. 7.1 Series BarriersRelations SeriesBarriers linked series will have the same current.

  3. Parallel RelationshipObstacles in parallel, the voltage between ujung2 obstacles are the same, amounting V

  4. Wheatstone Bridge BarriersWhen the price R1R3 = R2R4, then R5 is not working, thenMeanwhile, when R1R3 R2R4 ≠, then the series they will have to be replaced: R1, R2 and R5 was changed to Ra, Rb and Rc.

  5. Example:How many barriers to substitute between a and b?Determine barriers to substitute from a to b, if R1 = 1 Ω, R2 = 2 Ω, R3 = 8 Ω, R4 = 4 Ω and R5 = 5 Ω.

  6. 7.2 Rangkaian Listrik Sederhana • Rangkaian Terbuka • Rangkaian tertutup Dalam kenyataannya, arus listrik (I) akan ada bila rangkaian tsb merupakan rangkaian tertutup. Sedangkan untuk rangkaian terbuka tidak ada arus.

  7. Example:Determine the VAB, Vac, VBC.

  8. 7.3 Series Two LoopKirchoff Law INumber of branch flows toward a point equal to the number who leave it flows.Kirchoff Law IIIn a closed circuit, the algebraic sum electromotive force (E) is equal to the sum potential drop (IR).

  9. Example:Define I1, I2, I3.

  10. 7.4 Energy and PowerElectrical EnergyElectricityExample:At an indicated 100 W incandescent lamp, 220 V. Determine barriers tsb lights!Incandescent lamps of 60 W, 220 V, mounted on the voltage 110 V, determine the power which lights!
