Questions & Step-by-Step Solutions

What is the primary role of a gate in a MOSFET?
  • Step 1: Understand that a MOSFET is a type of transistor used to control electrical signals.
  • Step 2: Identify the three main parts of a MOSFET: the gate, the drain, and the source.
  • Step 3: Recognize that the gate is like a switch that can turn the current on or off.
  • Step 4: Learn that when a voltage is applied to the gate, it creates an electric field.
  • Step 5: Understand that this electric field allows current to flow between the drain and source.
  • Step 6: Conclude that the primary role of the gate is to control the current flow by applying a voltage.
