Fichas del conjunto (28)
- 1—RESISTOR
Limits current or controls voltage
- 2—VARIABLE RESISTOR
Limits current or controls voltage, but resistance value can be changed to vary current/voltage
- 3—NON POLARIZED CAPACITOR
Stores an electrical charge. Non-polarized means there is no positive or negative terminal
- 4—POLARIZED CAPACITOR
Stores an electrical charge. Polarized means there is a positive and negative terminal which must be connected
- 5—DIODE
Allows current to pass in one direction only
- 6—ZENER DIODE
A special diode usually used as a voltage regulator
- 7—LED
Light Emitting Diode: Solid state device which converts electrical energy directly to light
- 8—INCANDESCENT LAMP
Converts electrical energy to light by heating an element to the point that it glows brightly
- 9—SPST SWITCH
Single pole single throw switch. 2 terminal mechanical device to open or close a circuit for control
- 10—DPDT SWITCH
Double pole double throw switch. 6 terminal mechanical device which can switch 2 circuits between 2 possible connections
- 11—NORMALLY OPEN PUSHBUTTON
Normally open (off), but closes (turns on) when pressed
- 12—NORMALLY CLOSED PUSHBUTTON
Normally closed (on), but opens (turns off) when pressed
- 13—POSITIVE SUPPLY
Positive source terminal in a circuit
- 14—GROUND
Usually the negative source terminal in an electronic circuit
- 15—BATTERY
Source which converts chemical to electrical energy
- 16—POWER PLUG
Plug for domestic AC power source
- 17—AC ADAPTER
Plug directly into AC outlet and has DC low voltage output - 18—UNCONNECTED WIRES
Two wires not connected. Note the absence of a dot on the left
- 19—CONNECTED WIRES
Two wires which are connected as indicated by the dot
- 20—LDR
Light dependent resistor: Resistor which offers high resistance in the dark and less in light
- 21—NPN TRANSISTOR
3 terminal solid state device which may be used as a switch with a very sensitive input. Note the NPN emitter points away from the base
- 22—PNP TRANSISTOR
3 terminal solid state device which may be used as a switch with a very sensitive input. Note the PNP emitter points toward the base.
- 23—SCR
Silicon Controlled Rectifier: Solid state latch which has a very sensitive input
- 24—PIEZZOELECTRIC BUZZER
Solid state device which directly converts electric to sound energy
- 25—BELL
Mechanical device which converts electric to sound energy via electromagnet
- 26—SPEAKER
Mechanical device which converts electric to sound energy via a voice-coil (electromagnet) and permanent magnet system.
- 27—MOTOR
Mechanical device which converts electric to mechanical energy (rotary motion)
- 28—VIBRATION SENSOR
2 terminal switch which employs springs or other easily moved devices to detect motion
