    difference between Active and Passive components

    In electronics,we often met the two terms:active components & passive components.

    Can anyone give me a clear definition about the two terms:active & passive?

    Are they have some relationship to "linear" & "nonlinear"?

    Is diode an ative component or passive component?

    Thanks!

    Re: difference between Active and Passive components

    Active devices : the devices in which the electron flow( current) can be controlled electrically.

    Passive devices : the devices where electron flow ( current ) cannot be controlled electrically.

    Linear and Nonlinear generally applies to Active devices, even if there is no Passive device perfect linear.

    Following the above definition, diode is an Active device.
