**Resistors in Series and Parallel**

2
Resistors : Series In a series circuit, all components are connected end- to-end, forming a single path for electrons to flow. When resistors are connected in series, the current in each resistor is the same.

3
Resistors: Series Total current in a series circuit depends on how many resistors are present and how much resistance each offers. The equivalent resistance can be used to find current.

5
Resistors : Series Series circuits require all elements to conduct.

6
Resistors: Parallel In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

7
Resistors: Parallel The sum of currents in parallel resistors equals the total current. Resistors in parallel have the same potential differences across them.

8
Resistors: Parallel The equivalent resistance must always be less than the smallest resistance in the group of resistors.
