Explanation:
P-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of MOSFET where a p-type semiconductor is used as the substrate. It operates in a way that the gate voltage controls the current flow between the source and drain terminals.
The following are the characteristics of a p-channel MOSFET:
• The source and drain terminals of a p-channel MOSFET are made up of p-type semiconductor material.
• The substrate of a p-channel MOSFET is made up of n-type semiconductor material.
• The gate of a p-channel MOSFET is made up of metal oxide and is separated from the channel by a thin layer of oxide.
• When a positive voltage is applied to the gate terminal, free carriers (holes) are attracted towards the interface between the gate and the channel. This creates an induced p-type channel between the source and drain which allows the flow of current.
• When a negative voltage is applied to the gate, the free carriers are repelled, and the channel is turned off.
Answer:
The induced channel is p type region which is induced by applying a positive potential to the gate is not true for a p-channel MOSFET.
Explanation:
In a p-channel MOSFET, the induced channel is a n-type region which is induced by applying a negative potential to the gate. This is because when a negative voltage is applied to the gate, the free electrons in the n-type substrate are attracted towards the gate, creating an induced n-type channel between the source and drain. This allows the flow of current between the source and drain.

Answer:
The induced channel is p type region which is induced by applying a positive potential to the gate is not true for a p-channel MOSFET.
Explanation:

This is because when a negative voltage is applied to the gate, the free electrons in the n-type substrate are attracted towards the gate, creating an induced n-type channel between the source and drain. This allows the flow of current between the source and drain.
