MOS-FET transistor as resistor

Very useful feature of mos-fet transistors: the dependance of channel resistance on gate voltage often used in circuits. For example for AGC in radio receivers (My old selfmade radio).
Smoothly change the gate voltage and see value of resistance.

Полезное свойство полевых транзисторов: зависимость сопротивления канала от напряжения на затворе часто применяется в схемах, например для АРУ в радио приёмниках (My old selfmade radio).

Попробуйте изменять напряжение на затворе и наблюдайте показания омметра.
