Q. |
## Which of the following relation is true about gate current? |

A. | ig=id+is |

B. | id=ig |

C. | is= ig |

D. | ig=0 |

Answer» D. ig=0 | |

Explanation: the fet physical structure which contains silicon dioxide provides infinite resistance. hence no current will flow through the gate terminal. |
