Answer / jackkkk

active Pertains to a circuit or device that requires
a power supply for its operation. This differs from a
passive circuit or device, which operates with no external
source of power.

Answer / rajesh

1)Passive components are those that doesn't have gain or
direction.
ex:In network analysis they are called electrical elements.
2)Active components are those that have gain or
directionality. They include semiconductor devices and
vacuum tubes (valves).

Answer / suresh

active and passive componet is capacitore and doide

Answer / girish

To sum it all up:
For those who can't understand the detailed working of these
components, just add the word "BIAS" with every component.
If biasing is possible its active otherwise passive. Biasing
has nothing to do with polarity.

Answer / rizwan ahmad tahir

The Active Components are those components which cannot
perform their basic function(for which they are made)without
external energy(electrical or other). Basically they need
external voltage for their activation. For Example
(1).Transistor cannot perform its operation without biasing
(2).Micro controller cannot work without Vcc
(3).LDR cannot perform its basic operation without light.
Similarly Thermistor,different ICs etc. are active components.

Passive components required no external energy to perform
their operation in other words they connected as it is in
the circuit and they perform their specific operation.
Examples: Capacitor,Diodes,inductors,resistors etc.

Answer / arun kumar surya

In electrical, computer or storage systems, passive
components are those that do not require electrical power
to operate (e.g., not capable of power gain). This could
include the chassis, capacitors, resistors or enclosures
that do not require electrical power to operate but would
exclude system components such as the power supply, fans,
storage device, transistors, diodes and other controllers
(called active components).

Answer / jeyakumar.r

Active component:
1)The active component are capable for amplifying on
processing an electrical signal.
2) The required an external force for there processing
e.g. transistors, FET, MOSFET tube devices(vacuum tubes).

passive components:
1) The passive component are not capable for processing.
2)It does not required any external force for there
processing
e.g. Resistors, capacitor, inductor, oscillator, led's, etc.

Answer / vishwas kumar

The components which have linear V-I characterstics are passive components e.g. resistor. capacitor, inductior.

And the components which does not shows linear V-I characterstics are active components e,g. transistor, diode, SCR .
