1. Circuit

2. What is a Circuit?
Electrical devices connected such that a pathway is created for the flow of electrical current.

3. Parallel Circuits
A Parallel Circuit has more than one path for electron flow. -

4. Parallel Circuits - Voltage is equal in each arm of the circuit
Current is shared between arms
Lights bulbs progressively get dimmer -

5. Series
Provides one path for electron flow - - - - - - - - - - - - -

6. Series Circuits All current flows through all components
Voltage is shared between components
All lights glow at an even brightness -

7. Parallel & Series Circuits So what’s the difference?
What happens if you take out one of the light bulbs?
