## Study Notes

### Electric Charge and Current

• The fundamental unit of electric charge is the coulomb (C).

### Electrostatic Force

• The electrostatic force between two charges is inversely proportional to the square of the distance between them.

### Interaction of Charges

• When two unlike charges (opposite signs) are brought close to each other, they attract each other.
• When two like charges (same sign) are brought close to each other, they repel each other.

### Electric Charge Distribution

• On a conductor, electric charge distributes itself evenly on the surface.

### Study of Stationary Electric Charges

• The study of stationary electric charges is called electrostatics.

### Superconductors

• Certain materials exhibit no resistance below a critical temperature, known as superconductors.

### Semiconduction

• Silicon is the principal material used in semiconduction.

### Semiconducting Materials

• Semiconducting materials allow electron flow easily under certain conditions and behave as insulators under other conditions.

### Electric Current Measurement

• The unit of measurement for electric current is the ampere (A).

### Electric Current Flow

• The flow of electrons through a conductor is called electric current.
