Gates are reverse biased

Gates are forward biased

Gates are forward biased with drain

Gates are reverse biased with source

Inductor

Resistor

Capacitor

Transistor

It has to dissipate more heat

Output taken from collector terminal

Base collector region is reverse biased

Collector region always operate with high voltage

Acts as an amplifier

Acts as an oscillator

Acts as an open circuit

Acts as a closed switch

Minimum distortion

Maximum current gain

Maximum voltage gain

Minimum signal to noise ratio losses
