What is the level of IG in FET?

Answer – A.

The level of I_G in FET will be zero amperes.

Solution

The detailed solution to the question, what is the level of I_G in FET provided here. 

Because silicon dioxide essentially insulates the gate of a FET, the DC into the gate is zero amperes. The semiconductor channel and the gate combine between the source and drain to produce a capacitor. 

This indicates that an AC input signal will result in an AC, whereas a DC input signal will result in a zero-ampere gate current.

In reality, just a very modest current is passing through the gate. Merely leak current; therefore, the DC is quite modest. But without a doubt, it is not zero but can be approximated to zero.

Hence, Option (A) is the correct answer.
