Unit 5 - Week 9 and 10 Outline

1.     Atomic Theory
- What do atoms consist of?
- What make a good conductor?
- What makes a poor conductor?
- Attraction of electrons

2.     Types of current flow
- Static Electricity
- Electricity Produce from Chemical Reaction
- Electricity Produce from Magnetism

3.     Conductors and Insulators
- What makes a good conductor?
- What makes a good insulator?

4.     Parts of an Electrical Circuit
- Conductor
- Insulator
- Load

5.     Voltage, Resistance, and Current
- Electric Potential Difference
- Resistance
- Current Flow

6.     Electrical Energy
- Watt and Kilo-watts
- Power Factor

7.     Ohm’s Law
- E=IXR
- I=E/R
- R=E/I

8.     Summary
- States of matter are: solid, liquid, or gas.
- Atoms are the smallest particle and are made of electrons, protons, and neutrons.
- Alternating current is produced from the induction of magnetism into a coil of wire.
- Direct current is produced from a chemical reaction into metal plates.
- Energy can be transferred into different forms of energy, i.e., electrical energy into mechanical energy.
- Ohm’s law is used to determine voltage, resistance, and current in electrical circuits.
- Voltage is the force that pushes electrons through a circuit.
- Amperage is the flow or movement of electrons in a circuit.
- Resistance is the impedance of electrons flow in a circuit.
