since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason

A FET is called a voltage controlled device because the current between the drain and the source is controlled by the voltage at the gate with reference to the source (Vgs)
-
The gate voltage alters the conductivity of the channel between the drain and the source by creating an electric field
-
The FET has a very high input impedance, which means it requires very little current to operate.

What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
Why FET called current controlled device?
BJT is a current controlled device because its output current is dependent upon the current in the base while for FET it is controlled by the voltage at the gate terminal of the transistor. BJT is a current controlled device because its base current is not zero while for a FET the gate current is zero
Why scr is called as bidirectional an controlled device?
Because it can control input voltage in both halves of cycle.
What is mean by Zero Voltage Switching?
turn on and turn off a device and act as a switch is called as zvs
Difference between Threshold voltage and knee voltage?

What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
What device is also called a rectifier?
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
How can you change dc voltage into ac voltage?
The device to do that is called an inverter.
What device is used to steer a ship?

Voltage drop.
What is the voltage rating of screw-guns?
In North America, if the screw gun plugs into a wall receptacle the voltage will be 120 volts. If it is a battery operated screw gun the voltage will be marked on the battery that operates the device.
What is the significance of operating point in transistor?
Basically, a Q-point of any device gives information about the operating current & voltage of that particular device..This would help us to know about the max. & min. current or voltage upto which the can be operated safely.
