1. OHM’S LAW Resistance

2. O HM ’ S L AW O HM ’ S L AW  Ohm’s Law: Is the relationship between voltage, current and resistance.

3. S ERIES C IRCUITS  A series circuit has only one path for the charges to follow.

4. C URRENT IN S ERIES C IRCUITS  In a series circuit, there is only one path for the current to follow.  Therefore, the current in all parts of the circuit will be the same.

5. R ESISTANCE IN S ERIES C IRCUITS  Putting two resistors in series with one another further restricts the current flow.

6. P OTENTIAL D IFFERENCE IN S ERIES C IRCUITS

7.  in any closed circuit loop, the sum of the potential difference drops through all the components must be zero.

8. P OTENTIAL D IFFERENCE IN S ERIES C IRCUITS

9. S ERIES C IRCUITS Determine the current, total resistance, and voltage drops through all the resistors in the circuit

10. S ERIES C IRCUITS

11. P ARALLEL C IRCUITS  A parallel circuit is a closed circuit in which the current has more than one path, or branch, to follow

12. C URRENT IN P ARALLEL C IRCUITS

13.  Kirchhoff’s current law, which states that the current entering junction must be equal to the current leaving the junction.

14. R ESISTANCE IN P ARALLEL C IRCUITS

15. P OTENTIAL D IFFERENCE IN P ARALLEL C IRCUITS  Kirchhoff’s voltage law : the sum of the potential difference drops through all the components must be zero.
