Questions & Step-by-Step Solutions

What is the primary role of the gate in a MOSFET?
  • Step 1: Understand what a MOSFET is. A MOSFET is a type of transistor used to control electrical signals.
  • Step 2: Identify the parts of a MOSFET. It has three main parts: the gate, the drain, and the source.
  • Step 3: Learn about the gate. The gate is like a switch that controls the flow of electricity.
  • Step 4: Know how the gate works. When you apply a voltage to the gate, it creates an electric field.
  • Step 5: Understand the effect of the electric field. This electric field allows or stops the current from flowing between the drain and source.
  • Step 6: Conclude the role of the gate. The primary role of the gate is to control the current flow by applying a voltage.
