"Pinch of voltage" is not a widely recognized term in electrical engineering or physics. It may refer to a specific concept in a localized context or be a colloquial expression. If you meant "pinch effect" related to voltage, it typically describes a phenomenon in plasma physics or semiconductor devices where a current flow is restricted or controlled. Please provide more context if you're referring to something specific!

What is cut off voltage of jfet if its pinch off voltage is 5v?
5v
What is meant by pinch off voltage in fet?
Pinch-off voltage in a Field Effect Transistor (FET) refers to the specific gate-to-source voltage at which the channel conducting current begins to 'pinch off' or constrict. Beyond this voltage, increasing the gate voltage does not significantly increase the drain current; instead, the current becomes relatively constant as the channel narrows and limits the flow of charge carriers. This phenomenon is crucial for the operation of FETs in saturation mode, where the device is used for amplification and switching applications.
Pinch off does not mean current off and pinch 0ff condition current zero?
as voltage on the gate increases it will reach a point where any further input will not effect further.
As the drain voltage is increased for a junction FET in the pinch off region then the drain current?
Remains constant
2 What is Pinch-off voltage of JFET?
To find out the qualitative response to changes in Vgs and Vds, consider Vgs =0. In response to a small applied voltage Vds, a n-channel JFET acts as a simple semiconductor resistor and Id increases linearly with Vds. With increasing current, the ohmic voltage drop between the source and the channel region reverse biases the junction and the conducting portion of the channel begins to constrict. because of the ohmic drop along the length of the channel itself, the constriction is not uniform but is more pronounced at distances father from the source. Eventually, a Vds is reached at which the channel is "pinched off". At this voltage, Id begins to level off. and approach a constant value. It is not possible for the channel to close completely and reduce Id to zero. If that were the case, then the ohmic drop required to provide the back biasing would be lacking.Id is not equal to zero at Pinch off voltage.Thus, pinch off voltage can be defined as the gate reverse voltage that removes all the free charge from the channel.

What happens in n channel at pinch off voltage that the drain current becomes constant?
At pinch off voltage, the channel is blocked at its maximum. (depletion region blocks almost entire channel, so no charge exchange). Therefore, no drain is flown through the channel.
As the drain voltage is increased for a junction FET in the pinch off region then the drain current?
Remains constant
How do you Find the pinch-off voltage for a MOSFET?
1. Look up the data sheet (specification sheet) and get it from there. 2. Set it up with a voltage supply from source to drain, apply a bias voltage to the gate, measure the bias voltage to just cut off the drain current.
