Conductor definition - permits electric current to pass through
Insulator definition - restricts electric current from passing through
Examples of Conductors:
1. Silver
2. Copper
3. Steel
4. Aluminum
5. Gold
Examples of insulators:
1. Glass
2. Rubber
3. Plastic
4. Styrofoam
5. Paper
Differences between insulators and conductors:
1. Magnetic Field:
In Conductors: stores energy
In insulators: Do not store energy
2. Thermal Conductivity:
In Conductors: High
In insulators: Low
3. Covalent bond;
In Conductors: Weak
In insulators: Strong
4. Resistance:
In Conductors: Low
In insulators: High
Examples of semiconductors:
1. Silicon
2. Germanium
3. Gallium arsenide
