Resistors are used to limit current or divide voltage and can generate heat. Capacitors store energy in the form of charge and are measured in Farads. Diodes only conduct current in one direction, while transistors can amplify or switch electronic signals and have emitter, base, and collector terminals.
Basics of Electronics
- 1. BASICS OF ELECTRONICS Resistor Capacitor Transistor Diode
- 2. RESISTORS Resistors are used to limit current or divide voltage and in some cases, generate heat. Used for driving circuit which requires low current and voltage than available. A two terminal non-polar component Unit of resistance is ‘Ω’.
- 5. Practical Use…. • To reduce the current flowing in circuit, use resistance in parallel. • To reduce the voltage for any circuit, use resistance in series.
- 6. CAPACITORS A two terminal electronic component which stores energy in form of charge. Capacitance is a measure of a capacitor's ability to store charge. Measured in Farads(F) {μF or pF}
- 7. Types of capacitors Polarised: Specified +ve and –ve terminals Non Polarised: No defined terminals
- 8. Practical use • Timer Circuits. • Clipper & clamper circuit. • DC filter circuits.
- 9. DIODES • A two-terminal electronic component that conducts electric current in only one direction.
- 10. The direction of arrow shows the only possible direction of current.
- 11. Types of diodes • LED (Light Emitting Diode) Emits light when provided with power supply. • Photo Diode Generates Current when it is exposed to light.
- 12. TRANSISTOR • A transistor is a semiconductor device commonly used to amplify or switch electronic signals. • The three terminals are Emitter, Base and Collector
- 13. • Transistor are of two types: 1-> n-p-n A straight switch 2-> p-n-p A inverted switch
- 14. Practically used… • As a switch • As an amplifier
