Questions & Step-by-Step Solutions

What is the main difference between N-channel and P-channel MOSFETs?
  • Step 1: Understand what a MOSFET is. A MOSFET is a type of transistor used to control electrical signals.
  • Step 2: Learn about charge carriers. Charge carriers are particles that carry electric charge. In electronics, these are usually electrons and holes.
  • Step 3: Identify the type of charge carrier in N-channel MOSFETs. N-channel MOSFETs use electrons as the charge carriers.
  • Step 4: Identify the type of charge carrier in P-channel MOSFETs. P-channel MOSFETs use holes as the charge carriers.
  • Step 5: Compare the two types. The main difference is that N-channel uses electrons (negative charge) while P-channel uses holes (positive charge).
