Basics of Electronics (Resistor, Capacitor, Diode and Transistor)

Transcript of Basics of Electronics

  • 1. BASICS OF ELECTRONICSResistor CapacitorTransistor Diode

2. RESISTORSResistors are used to limit current ordivide voltage and in some cases, generateheat.Used for driving circuit which requires lowcurrent and voltage than available.A two terminal non-polar componentUnit of resistance is . 3. Physical appearance 4. Color code table 5. Practical Use. To reduce the current flowing in circuit, use resistance inparallel. To reduce the voltage for any circuit, use resistance in series. 6. CAPACITORSA two terminal electronic componentwhich stores energy in form of charge.Capacitance is a measure of acapacitor's ability to store charge.Measured in Farads(F) {F or pF} 7. Types of capacitorsPolarised: Specified+ve and ve terminalsNon Polarised: Nodefined terminals 8. Practical use Timer Circuits. Clipper & clamper circuit. DC filter circuits. 9. DIODES A two-terminal electronic componentthat conducts electric current in only onedirection. 10. The direction of arrow shows theonly possible direction of current. 11. Types of diodes LED (Light Emitting Diode)Emits light when provided with power supply. Photo DiodeGenerates Current when it is exposed to light. 12. TRANSISTOR A transistor is a semiconductor devicecommonly used to amplify or switchelectronic signals. The three terminals are Emitter, Baseand Collector 13. Transistor are of two types:1-> n-p-nA straight switch2-> p-n-pA inverted switch 14. Practically used As a switch As an amplifier 15. MatlabInstallationAssemblingof RobotSolderingPCB
