1. Series and Parallel Circuits How to find the resultant resistance of an electronic circuit

2. Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.

3. Electronic circuit An electronic circuit is a closed path formed by the interconnection of electronic components through which an electric current can flow Basically an electronic circuit is a passageway or route in which electricity (a flow of material) can flow from start to finish.

4. Series circuit An electronic circuit in which there is only one path for electricity to flow. Same current in all components

5. Resultant resistance in series The total resistance is equal to the sum of all the resistances in the circuit. R total = R1 + R2 + R3…

6. Parallel Circuits An electronic circuit in which there is more than one path for the electricity to travel. Same voltage drop in each path.

7. Resistance in Parallel The resultant resistance of a parallel circuit is actually less than the smallest component. Think of it as electricity will take the path of least resistance. Some most of it will travel through the smallest resister and some will seep through some of the larger ones.

8. Resistance in Parallel The following is the formula for the resultant resistance of a parallel circuit
