| Resistance | The opposition to current flow. |
| Non Conductive | Very few free electrons, high resistance. |
| Good Conductor | Many free electrons, low resistance. |
| Increase Resistance | Current Decreases |
| Decrease Resistance | Current Increases |
| Symbol for Resistance | Omega |
| Factors that determines Resistance | Material used, Areal cross section, length, and temperature |
| Silver | Best conductor |
| Glass | Insulator |
| Small cross-section area... | has higher Resistance |
| Large cross-section area... | has lower Resistance |
| Resistance abbreviation | R |
| Unit of Resistance | Ohm |
| Carbon Resistor | Very common, inexpensive to make, change value with age. |
| Wire Wound Resistor | Used for high power applications |
| Carbon/Metal Film Resistors | High accuracy resistors |
| Potentiometers | Variable Resistors |
| SIP | Single Inline Package |
| DIP | Dual Inline Package |
| SMR | Surface Mount Resistors |
