1)Electric connections can be made with series or paralleled circuit

2)In a series circuit current flows on only one path

3)In a series circuit current is the same everywhere ( It = I1,= i2 = I3 )

4)In a paralleled circuit there is more than one pathway for current to flow.

5)In a paralleled circuit current in = current out but current isn’t the same everywhere ( It+ = I1 + I2 + I3 )

6)Kirchhoff’s current law states at any junction in an electric circuit the total current flowing in to the junction is equal to current flowing out of the junction

7) In a series circuit total potential difference is equal to the sum of potential difference across components

8)Increase in potential difference across the cell must equal the sum of decrease in potential difference. In series of circuits

9)Potential difference across components in parallel must be equal.

10)Kirchoffs voltage law states the algebraic sum of potential differences around any closed pathways or loop must equal zero.

11)Both these laws follow the law of conservation of energy

12)Often circuits are made up of both series and paralleled circuits

13)Boosting a car battery can be dangerous

14)TO do it properly connect the red cable to the positive terminal of each battery

15)Then attach the black to the live battery then slowly to a clean part of the engine

16)When removing the cables, remove the cable to the engine first

17)During boosting, the car with the live battery should remain off

18)This is to avoid damaging the electric systems of the cars

19)Caution, in some vehicles positive rather than negative terminals are connected to the engine

20)To avoid casing damage check grounding before the boosting process
