Abstract
- Electronic component that is solid-state
- Derived from Mechanical Relay which is Electromechanical, then followed by vacuum tube which is Electronic
2 main functions
- Switch circuit on & off automatically with a much smaller current
- Amplify Signals
Terminologies
Electromechanical
- A mechanical device which is electrically operated
- Move much slower compared to Electronic, because we are moving a physical piece that has billion times the mass compared to Electronic
- Less durable than Electronic
Electronic
- A component which is controlled by electric current aka a stream of electrons
- Move much faster compared to Electromechanical, because we are only moving a very small amount of electrons
- Much more durable than Electromechanical, because we are talking about atomic level, no moving parts on a physical level
