what is Active device and Passive device?..

Answer / hunny soni

Passive device don't have its own internal energy. To
operate these device we require external energy. Like
Resistor capacitor and inductor.

Active device don't need external energy. It has its own
internal energy. Like battery, and transistor etc.

what is Active device and Passive device?..

Answer / kunal s. thaker

ACTIVE DEVICE :- The device which can deliver power to other
element.

PASSIVE ELEMENT :- The device which is not able to deliver
power. But they get the power from ACTIVE DEVICES.

what is Active device and Passive device?..

Answer / ankur saxena

active devices are the devices in which we can control
current or flow of electron electrically i.e. by use of
current or voltage.
e.g. transistors,triacs etc
in passive devices we cant control it
e.g. resistor,inductor,capacitor.

Answer / mohit vashishtha

An active device is any type of circuit component with the ability to electrically control electron flow (electricity controlling electricity). In order for a circuit to be properly called electronic, it must contain at least one active device. Active devices include, but are not limited to, vacuum tubes, transistors, silicon-controlled rectifiers (SCRs), and TRIACs.

Components incapable of controlling current by means of another electrical signal are called passive devices. Resistors, capacitors, inductors, transformers, and even diodes are all considered passive devices.

Answer / sruthi

diode is not a passive device bcz due to some charge
carriers containing it(in pn junction).....some what it can
generate energy not as like that active device............

Answer / barsha

active divices- require some extrenal energy to be ready
for an operation. these are the devices which increases the
amplification.
passive devices- this devices does not require a source of
energy for operation. it only changes the phase and
decrease the amplitude of a sine wave.
