Study Notes
Introduction to Electronics
- Electricity is the driving force that provides most of the power for the industrialized world.
Types of Electric Sources
- Direct current (DC): unidirectional
- Alternating current (AC): bidirectional
Current Flow Theories
- Electron flow theory: current flows from negative to positive
- Conventional current flow theory: current flows from positive to negative
Definition of Electronics
- A branch of physics that deals with the emission, behavior, and effects of electrons
- Includes electronic devices, components, and equipment
Basic Electric Circuits
- A complete path (closed circuit) must exist for current to flow through a circuit
- If the switch is opened, the circuit becomes open and no current can flow
- A short circuit has very low resistance, allowing current to flow freely
