Electrics
* Components that transmit electricity and provide power to various vehicle systems.
*Includes:
* Battery
* Generator
* Starter
* Wiring
* Fuses and relays
Electronics
* Components that process, store and control electronic signals.
*Includes:
* Electronic control units (ECU)
* Sensors
* Drives
* Navigation systems
* Communication systems
Differences
* Electrical transmission: Electrical engineering deals with the transmission of electrical energy, while electronics deals with the processing and control of electronic signals.
*Voltage: Electrical systems typically operate at higher voltages (such as 12V or 24V), while electronic systems often operate at lower voltages (such as 5V or 3.3V).
* Amperage: Electrical components usually have higher currents, while electronic components usually have lower currents.
* Signal Processing: Electrical does not process signals, while electronics can process, store and manage large amounts of data.
Relationship
Electrics and electronics are closely linked in modern cars. Electrics provide power to electronic systems, while electronics monitors and controls electrical components.
For example, the engine ECU uses electronic signals to control fuel delivery and ignition, while the alternator receives mechanical energy from the engine and converts it into electricity to power various vehicle systems.
