Define pinch off voltage and the gate source cut off voltage?
If negative voltage is applied to the gate of a NMOS, it repels electrons from the channel region towards the bulk of the p-substrate and attaract holes from p-substrate towards the channel. The recombination between holes and electrons causes a deplation of majority carriers in the channel. Enough nagative gate voltage can cause the channel depleted of majority carriers and cuts off the current between the source and the drain. The least negative gate voltage causing this is called gate-source cut off voltage.
What is the difference between regulated and unregulated power supply?
in regulated the voltage will be a constant one and can't be variant but is in case of unregulated
How do you work thyristor?
The thyristor functions in such a way that when the anode voltage is greater than the cathode voltage , it is not triggered but only triggers when a gate signal is applied at the gate of the device.
Why the voltage remain constant after reaching the some point?
because it is being regulated.
Why is it thatFET is called a voltage operated device?
since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason
The term voltage regulated means that the?
membrane voltage gated ion channels open and close with changes in the membrane potential
What change does ACh cause in an ACh receptor?
ACh binds to each ACH receptor which causes opening of ligand-regulated ion gate and the creation of end-plate potential.
What is the main ion regulated by PTH?
I think Ca++Calcium ion

What kind of gated channels are involved in the generation of graded potentials?
chemically regulated gates, voltage regulated gates
What is happening to the voltage value of scr if its gate is triggered?
the anode-cathode voltage drops

Does a 1974 corvette have a voltage regulator?
it should have an internally regulated alternator
