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 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
