Study Notes
Electronic Components
Resistors
- A passive component that reduces voltage or current
- Measured in ohms (Ω)
- Types:
- Fixed resistors: have a fixed resistance value
- Variable resistors: can change resistance value
- Characteristics:
- Resistance (R): opposition to current flow
- Power rating: maximum power that can be dissipated
- Tolerance: percentage of deviation from nominal value
Diodes
- A semiconductor component that allows current to flow in one direction
- Types:
- Rectifier diodes: convert AC to DC
- Zener diodes: regulate voltage
- LED (Light Emitting Diode): emits light when forward-biased
- Characteristics:
- Forward bias: allowing current to flow
- Reverse bias: blocking current flow
- Breakdown voltage: maximum voltage before diode breaks down
Transistors
- A semiconductor component that amplifies or switches electronic signals
- Types:
- Bipolar Junction Transistors (BJTs): use both positive and negative charge carriers
- Field-Effect Transistors (FETs): use voltage to control current
- Characteristics:
- Amplification: increasing signal strength
- Switching: turning on or off
- Current gain: ratio of output to input current
