Answer / arvind kr shah
ACTIVE COMPONENTS
The Switching Device like Transistor,MOS-FET, FET, SCR etc. are active Component
PASSIVE COMPONENTS
The components like Resistors-R, Inductors-L, and Capacitors-C etc. are passive components.

Answer / matheen
passive means inactive it is just operating by power supply to an input 250ampAC= resister,capacitor,inductor,diode,transformer=output....what ever it given it could be change the by there functions in the circuit.output is just operating the input current by protecting the over voltage and current.. diode means it just changing the ac to dc or only forward by protecting the reverse unwanted power that-it.it just take the in power big=output small are some els what ever the in the function capacitor ,inductor,diode
active means just a moving,transistor,op-amp..whatever power will give in the transistor,op amp in it having a amplifier and gain-activity it will move to the out put...it just take the input power =out put gain,amplifier

Answer / abhiranjan chaudhury
active component are those component that can boast or
amplify the signal strength e.g. capactor, diode, diac, triac

Answer / joseph p. v.
Passive Electronic Devices include Resistors, Capacitors,
and Inductors which modify the current in the circuit and
have a fixed function value. Eg a 10k resistor has the same
value throughout its use.
Active Electronic Devices inlcude 1N, 2N, and 3N
semiconductor diodes transistors and SCR which modify and
control current in a circuit by way of changing
electrostatic forces in the device. The diode has an
electrostatic field in the junction that allows current to
flow in only one direction. The transistor has an
electrostatic field that can be biased so that it can switch
on or off the current or control it. The SCR can control AC
current.

Answer / jeetendra kadam
The component which takes actual part in circuit i.e.
amplify,conversion r active components.
(diode,transistor,mosfet,igbt) whereas components which
passes/stores the energy r passive components
(resistor,capacitor,inductor)

Answer / wolf
An active sensor/component requires an electrical power
source to work. A passive one does not.
Ultrasonic sensors, radar, and video cameras are active. A
strain gauge (whose resistance changes with pressure
applied) is passive. Some types microphones are active
while others (like piezoelectric microphones) are passive.
THey generate an output with only the input energy they are
sensing. They do not need a power source to generate an
output (though the output will usually be very low and need
to be amplified with an active device).
Thermocouples and thermopiles are passive. THey generate a
voltage output using the temperature energy they are
sensing. They do not require a battery to make their
output. But it is very weak and probably needs to be
amplified with an active device like an op-amp.
Some RFID tags are passive, others are active. The active
ones need a battery present to work. THe passive ones take
the RF energy being transmitted by the base unit, modify it
somehow, and reflect it back out to be received by the base
station, but they have a much shorter range than the active
ones.

Answer / sanchit mehta
active components are those components which produce energy
in the form of voltage and current ex- transistors, op
amp , etc.
whereas passive components are those which store energy in
the form of voltage and current. ex- resistors, capacitors,
inductors, vacuum tubes, etc.
