1. Electrical Circuits

2. Current electricity The flow of electric charges
Electrons (negative charge) moving through a wire

3. Electrons have the following properties:
Speed – current
Energy - voltage

4. What is a circuit?
An unbroken loop from one battery terminal to the other battery terminal

5. Basic Electrical Circuit

6. States of Circuits
Open Circuit – a loop in which there is a break in the circuit
Closed Circuit – a loop in which there is no break in the circuit
A break in the circuit is created by the control device (typically)
