Study Notes
What is Electricity?
- Electricity is a form of energy resulting from the movement of charged particles, such as electrons.
- It is a secondary energy source, meaning it is derived from other energy sources, like coal, natural gas, or nuclear reactions.
Electric Charge
- Electric charge is a fundamental property of matter, found in two forms: positive and negative.
- Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other.
- The unit of electric charge is the coulomb (C).
Electric Current
- Electric current is the flow of electric charge, typically measured in amperes (A).
- It is the movement of electrons through a conductor, such as a wire.
- The direction of current flow is from positive to negative.
Voltage
- Voltage, or electric potential difference, is the force that drives electric current.
- Measured in volts (V), it is the potential difference between two points.
- Voltage can be thought of as the "pressure" pushing electric charge through a circuit.
Resistance
- Resistance is the opposition to electric current, measured in ohms (Ω).
- It depends on the material, length, and cross-sectional area of a conductor.
- Higher resistance reduces the flow of electric current.
Electric Circuits
- An electric circuit is a path through which electric current flows.
- A closed circuit allows current to flow, while an open circuit does not.
- Series and parallel circuits are two common configurations.
Types of Electric Current
- Alternating Current (AC): periodically reverses direction, used in household power distribution.
- Direct Current (DC): flows in one direction, used in electronic devices.
Electricity Applications
- Power generation and distribution
- Electronic devices, such as computers and smartphones
- Industrial applications, like manufacturing and transportation
- Medical equipment and medical treatments
