it has high input impedance
• High Input Impedance Amplifier. • Low-Noise Amplifier. • Differential Amplifier. • Constant Current Source. • Analog Switch or Gate. • Voltage Controlled Resistor. • JFET as a Switch • JFET as a Chopper • JFET as a Current source • JFET as a Amplifier • JFET as a Buffer
1-BJT is bipolar while JFET is unipolar. 2-BJT has low input impedence while JFET has high input impedence. 3-JFET has low power discipation as compared to BJT. 4-JFET has low noise as compared to BJT. 5-BJT is current controlled while JFET is voltage controlled. 6-JFET is mostly used in digital circuits.
If you mean JFET, it is because the gate junction is reverse biased.
Your input device, for example a mouse, is connected to your input medium, your computer. an input device is a device that is used to input or helps to enter data into the computer and an input medium is where the input device is detected e.g the slots
scanner is an input device. it is used to store data in a computer.
a CD is an output device that can be used as a storage or input device
Depends. What is the device?
input device
The most used input device on a computer is the keyboard.
Usually a joystick is used as an input device for gaming purpose. A keyboard is also used for such purpose
No, Mouse is an input device. Because mouse is used to instruct the computer where to point the cursor and anything that is used to instruct computer in any way is an input device. Output Devices show the processed data by a computer for e.g. a monitor shows where the cursor is by processing the input from a mouse.
