Because resistor is not required to operating voltage.naturally resistive material like carbon is restrict of voltages.Active components means its requiered to operating voltage or Vcc or Vdd example transistor and fet etc..
A2
Passive components need no external control inputs. They have a natural effect on a voltage applied to them.
A3
Resistor are called passive component because their resistance value does not change even when the level of applied voltage or current to it is changed.also resistance value remains same when the applied voltage ac or dc.

∙ 12y agoBecause in it's initial design it cause a certain amount of resistance that won't change unlike a relay for instance. A relay actually has an action that changes what it will accomplish. A switch would be another example of an active component. But the poor little resistor just sits there doing the same thing over and over.

Of the three, the resistor is the passive component. Both the capacitor and inductor are reactive components. Capacitors store energy through electrostatics. Inductors store energy through electromagnets. Voltage lags current by 90 degrees in a capacitive circuit. Current lags voltage by 90 degrees in an inductive circuit.

Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Rectifier a passive component?
yes, it is a passive component.
Discrete products in semiconductors?
Resistors, capacitors, diodes any component that is a recognized item byitself as a single component.
What is the difference between active and passive component?
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
What is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Why capacitor is an active component?
A: If you are reading this out of a book that book is wrong resistors capacitors coils are passive components NOT active
Where are resistors placed to control voltage and current?
A: A RESISTOR is a passive component it cannot control voltage these components and/or current it can however limit
Is the inductor a passive component or active component?
passive
Rectifier a passive component?
yes, it is a passive component.
What are Passive components and its characteristics?
A passive component does not interact as an active component like an amplifier
Why active filters so called even though uses passive resistors?
It has to have resistors but an active filter will alsol have an active device, usually an op-amp, while a passive filter has only passive components and needs no power supply.
What is passivation?
Passive means, not active. It has a number of applications - in grammar a verb can be passive, in electronics, components such as resistors, capacitors or inductors are passive (transistors are active).
Discrete products in semiconductors?
Resistors, capacitors, diodes any component that is a recognized item byitself as a single component.
How does active termination improve upon passive termination?
In active termination scheme it removes the thermal noise which results in the passive termination due to the end resistors..
Is transistor active or passive element?
it is a active component.
What is veritable resistor?
Variable resistor is a passive component where we can vary its resistance simply by rotating it's head .These resistors are available from few ohm to several mega ohm. and are used for regulator or gain control in amplifier circuits. It is three terminal device.
