what are active and Passive Components?

Answer Posted / sacchidanand teke

ACTIVE COMPONANT:-ACTIVE components increase the power of a
signal and must be supplied with the signal and a source of
power.
Examples are bipolar transistors, field effect transistors
etc. The signal is fed into one connection of the active
device and the amplified version taken from another
connection.
In a transistor, the signal can be applied to the base
connection and the amplified version taken from the
collector. The source of power is usually a dc voltage from
a battery or power supply
Passive Componant:-PASSIVE components do not increase the
power of a signal.
They often cause power to be lost.
Some can increase the voltage at the expense of current, so
overall there is a loss of power.
Resistors, capacitors, inductors and diodes are examples of
passive components.
Integrated circuits contain both active and passive
components.
Since they usually increase the power of a signal and
require a source of dc power they are treated as active
devices.
