1. Parallel Circuits

2. What is a parallel circuit?
Several paths (branches) for the current to take

3. How many different pathways are there?
As many as you want.
Usually more than 2

4. What happens when you add a branch?
If you add more paths more opportunities for electrons to flow
Overall resistance decreases

5. Which type of circuit is in your house?
Parallel of course!

6. How do you know?
If a light burns out, the rest of the house keeps working
Resistors are simply replaced

11. Types of circuits COMPARE CONTRAST 1 or more paths Multiple resistors
They both work
Add resistors changes the resistance
1 path, 2 or more paths
1 goes out, all out or stay on
1 resistor, to multiple resistors
